Red fiber lasers were the earliest models developed for the cutting-edge microscopy platforms built in the laboratories of Dr. Stefan Hell, and flow cytometry platforms tested in the lab of Dr. William Telford of the Core Flow Cytometry Facility at N.I.H. where beam quality, reliability, and stability continue to be of the utmost importance.

Serving North America, RPMC Lasers offers a wide range of red diode, DPSS, and gas lasers between 620nm and 699nm. We offer pulsed and CW lasers and modules, including single- and multi-emitter, free-space and fiber-coupled laser diodes, bars (arrays) and stacks, wavelength stabilized laser diodes, multi-wavelength, laser diode modules, HeNe lasers, CW DPSS lasers, line modules, and more, available with output powers ranging from 0.5 mW up to 5 W, with packaging at all levels of integration from TO can through turnkey system. Standard and custom options available. Let RPMC help you find the right laser today!

Our suggestion: place a preview in a suitable encyclopedia article! (That feature is offered as part of our advertising package.) For example, the paper preview shown above would well fit into our articles on laser diodes and diode bars.

CNI offers red lasers with many wavelengths from 607 nm to 760 nm. Some of them are pure diode lasers, while others are diode-pumped solid-state lasers.

White papers and videos are great instruments for creating an interest in your technology and demonstrating the capabilities of a company. But how to publicize them, reaching the right audience?

Getting a camera for my stream this weekend and want to make sure lighting is good 👍🏻 anyone have suggestions for a quality ring light that won’t be insanely expensive? 😂

Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet. In case you can still not match your wavelength of choice, contact TOPTICA – and chances are very high that we can provide it within very short time.

This article deals with lasers emitting in the red spectral region, i.e. with a wavelength roughly around 625–700 nm. The following types of red lasers are the most common:

TOPTICA offers a large variety of wavelength-selected single-mode laser diodes. Among more standard laser diodes you will also find "rarities", i.e. diodes with output wavelengths that only TOPTICA provides. The diodes can be purchased separately. In addition TOPTICA can integrate any diode from the stock lists into a tunable diode laser system: Fabry–Perot or AR-coated laser diodes may be integrated into a diode laser systems, DFB/DBR laser diodes into a DFB pro and Tapered Amplifier into an TA system.

SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes at 635 nm and 660 nm as stock items or associated with a CW laser diode driver or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers. The single mode laser diodes (Fabry–Pérot laser diode ) can reach high power in nanosecond pulse regime up to 50 mW. Most turn-key diode & driver solutions are optimized for single-shot to CW performances with pulse width lengths down to 1 ns. The laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal.

Wavelengths from 620 nm to 775 nm are available in either an OEM compact package, and/or a 2RU rack mountable package with integrated power supply and are equipped with a user-friendly graphical user interface for ease of setup and operation. MPB offers an optional fiber coupling service which provides the user up to 1 watt out of the fiber.

Light from lasers operating at somewhat longer wavelengths, such as 750 or even 800 nm, can still be perceived as red light, if it is sufficiently intense. (There is no sharp boundary between the visible and the infrared spectral regions.) It can, however, be hazardous to view such light because such intensity levels required for good visibility can damage the retina.

Red lasers are applied e.g. as laser pointers, for bar scanners and other laser scanners, for optical data recording or retrieval (e.g. on DVDs), for laser projection displays, for interferometers, for pumping of certain solid-state lasers (e.g. Cr:LiSAF or Cr:LiCAF), and in medical therapies (e.g. photodynamic therapy).
