You might be able to spot some pitfalls in your home’s security by seeing how people get in or where they go. But the aerial images aren’t always high quality. (They’re borrowed from third-party sources.)

The superior beam quality and long-term stability of the Astrella regenerative amplifier makes it an ideal turnkey engine for experiments in extreme operating regimes that formerly required complex sources and considerable laser expertise.

There’s no reason to chuck your Spotlight Cam in favor of the Floodlight Cam if you just want brighter lights. Instead, you can hardwire your existing external lights to the Spotlight Cam mount. They’ll turn on whenever the camera detects motion. How nifty is that?

There’s also no ability to adjust the resolution, frame rate, or bit rate to improve streaming over slow internet connections.

Scientists at Elettra-Sincrotrone, Trieste, Italy, use a novel scheme to generate VUV pulses at 10.8 eV (115 nm) from a Coherent Monaco amplifier.

An innovative and commercially available set-up for multidimensional coherent spectroscopy coupled with microscopy to study spatially-resolved optical coherence times, coherent coupling between excitons, and charge transfer in a TMD heterostructure.

Ultrafast laser pulses enable the study of fast events in all kinds of materials. Many of these studies use some type of pump-probe method where one pulse excites the sample and another pulse interrogates the outcome. That’s because the best tool to match the incredible time resolution of a UF laser pulse is another UF laser pulse! Some of the experimental setups are therefore quite complicated. That’s why we emphasize simplicity and reliability in all our ultrafast lasers – so you can put all your focus on your experiment, never the laser.

We like the utility of the free Ring app. You don’t have to pay to get push notifications whenever motion is detected. Many brands don’t offer that. With Ring, it’s truly possible to self-monitor your camera for free.

Ring recommends installing the Floodlight Cam nine feet high. At this height, the motion sensor detects movement up to 30 feet away, and the camera clearly shows people’s faces. Mounting the Ring Floodlight camera lower than nine feet reduces the motion sensor’s range, and mounting it higher reduces the camera’s image quality.

The Ring Spotlight Camera is better suited to small areas because its light only reaches 375 lumens. It has black-and-white night vision instead of color vision and can be purchased with different power-supply options. The Floodlight works better in large areas where you can mount it at the recommended height of 9 feet.

Although the latest version of the Ring app features geofencing, it doesn’t currently support floodlight automations. This means you can’t schedule the lights to turn on/off when you (and your phone) enter or exit the geofence perimeter. But Ring works with IFTTT, so you can set up an applet to perform this function instead.

2D techniques like 2DIR, 2DES, and 2DSFG provide unique data connecting energy levels of biomolecules, proteins, catalysts, and advanced materials.

Discover the Coherent Monaco 1300, a one-box ultrafast 1300 nm light source with a pulse width shorter than 50 fs developed for three-photon imaging.

This isn’t necessarily a bad thing. You could set it up to illuminate an area of your backyard that’s accessible only from the house—lighting things up while cutting down on notifications. On the other hand, it would be frustrating to not know what’s triggering the lights if the movement always stays out of frame.

Learn how an ultra-stable femtosecond amplifier enables high data output in two-dimensional infrared spectroscopic studies of biological membranes and surfactants.

The floodlights automatically turn on when motion is detected but only at night. They also automatically turn off about 30 seconds after sensing motion, and you can adjust this time from the Ring app.

But this isn’t the best camera choice if video quality is your number-one concern or if you need free video storage. We’re also looking forward to a battery-powered, solar-powered, or plug-in option for a more DIY-friendly experience.

The floodlight motion sensor also has a wider field of view (270°) than the camera (140°). Depending on how you customize the activity zones, the floodlights might kick on before the camera catches any movement.

We’re hopeful that Ring will release battery- and solar-powered versions of the Floodlight Cam like they did with their Spotlight Cam.

To review Ring Floodlight Cams, we compared the specs of each model (Plus and Pro). We also stacked those specs against other floodlight cameras and outdoor security lights on the market. We read reviews, viewed third-party footage, read the user manuals and customer support documentation, and got our hands on the Floodlight Cam Plus. Read more about how we review products on our methodology page.

Both Ring Floodlight Cams feature two motion sensors: one for the floodlights and one for the camera. This makes the Floodlight Cam super customizable.

But what about those times when you can’t check the live feed? Ring should have added an “arm/disarm” function with the siren to make this an even better outdoor security camera.

The Ring Floodlight Cam is only available as a hardwired unit. That means you’ll have to cut into a wall or ceiling, access existing electrical wires, and splice in the unit—while following all electrical safety protocols, of course.

Online shopping for lasers, optical fibers, power meters and sensors, accessories, and much more on Coherent online has never been easier.

The floodlight’s motion sensor is already split into three 90° zones. You can adjust the sensitivity of each zone or turn them off entirely, but you can’t draw a unique activity zone for the lights.

Ultrafastoptics

From the Ring app, you can draw motion activity zones for the camera to make sure you get notifications only when it counts. For example, if your neighbor’s yard ends up in the camera frame, you can make sure the camera ignores motion in that area.

The combination of high pulse energy and long term stability from a Coherent Astrella ultrafast amplifier enables precise characterization of how molecules are bound to surfaces, with implications from green energy catalysts to electronics and biological membranes.

The Ring Floodlight Cam Plus records in 1080p at 15 fps. That’s sufficient for many people, but not anything to write home about.

Ultrafast spectroscopywikipedia

The coolest feature in this upgraded version is “bird’s eye view,” which shows an aerial view of your home in the corner of the main screen. Yellow dots appear wherever motion was detected, letting you see how someone entered the motion activity zone and where they went.

Ring Alarm's new Floodlight Cam Plus improves on the Ring Floodlight Cam by offering color night vision, incredibly bright floodlights, and even more motion activity zones. But it only comes in a hardwired version, and its video quality is just okay. Ring’s latest release—the Floodlight Cam Pro—offers better sound quality and connects to dual-band Wi-Fi, but doesn’t offer upgraded video quality.

The app also features an on/off toggle for the lights, and you can set up light schedules to keep the floodlights on throughout the night.

We like that the floodlights on this Ring cam are bright enough for startling a trespasser or illuminating the driveway for a late-night trash run.

If you’re a seasoned DIYer, maybe that’s no sweat. Ring provides instructions to help you get it right. But if you’re not confident about tackling this yourself, you’ll have to call an electrician, and that’s an extra expense.

Amplifier thermal stability is critical. Our chamber runs at up to 950 degrees C internally and heats the lab significantly during long experiments. The power, beam shape, and pointing of Astrella are all unaffected by these ambient changes.

Astrella integrated kHz Ultrafast Ti:S Amplifiers deliver better data and lower data costs to enable 2D spectroscopy, THz studies, fs micromachining, and more.

The superior beam quality and long-term stability of the Astrella regenerative amplifier, as well as the intrinsic flexibility of the Monaco ytterbium fiber amplifier, make them ideal turnkey engines for experiments in extreme operating regimes.

Coherent two-dimensional spectroscopy (CMDS) represents a powerful group of spectroscopic techniques with the unique ability to reveal couplings between different states of a system, as well as their relaxation timescales.

“The high reliability and operational simplicity of Coherent ultrafast lasers are critical advantages because of the optical and electronic complexities of our imaging method.”

We think Ring missed out on a great customization opportunity with the Floodlight Cam siren. First of all, we’re glad the 105 dB siren exists since it’s a great way to send a trespasser skedaddlin’. We also like that you can decide to turn on the siren after checking the live feed.

The main downside to the free version is that you can't record any videos. With the Ring Protect Basic plan, you can only record from one device. If you love your Ring Floodlight Cam and want to try other Ring products with video recording, you’ll have to upgrade to the $10/mo. Plus plan.

The Ring Floodlight Cam is one of many cameras in Ring's repertoire that works with end-to-end encryption (E2EE). This feature keeps your camera feed and recorded clips strictly private under digital lock and key.

They shine at 2,000 lumens. For perspective, the Ring Spotlight Cam’s light is just 300 to 375 lumens, and our favorite motion detector light tops out at 1,800 lumens.
