Another very handy feature is "data logging". This allows you to set up the QUAD-4TRACK to follow the displacement, energy and/or power of your laser over several minutes, hours or even days. Need to measure the "beam steering" of your laser as it warms up? This is how you do it! Need to measure the beam displacement vs laser repetition rate or energy level? Data logging will help you measure it!

Portable laser power meter for up to 250 W with flexible calibration options so the customers only pay for what they use. Includes 3 measurement modes : SSP, CWP and SSE.

Gauge sizes are a little counterintuitive at first, because they’re literally backwards: the smaller the number, the larger the size.

Gauge sizes go up (or down, depending on how you look at it) in even numbers from there, so the next largest size from an 18g is 16g, then 14g, then 12g, and so on.

Laser beamAnalysis

The gauge measuring system was created based on the number of holes the wire was pulled through. For example, a 10 gauge wire had been pulled through 10 holes, so it was much thinner than a 1 gauge wire, which was just pulled through one. That’s why the larger the number is, the thinner and smaller the actual measurement is.

The gauge system was first created for measuring the thickness of wire (like electrical wiring or structural cables). It’s been in use for hundreds of years, at least since the 1700s.

The QUAD-4TRACK is a laser position sensing system designed to support our unique pyroelectric quadrant detectors, QUAD-P and QUAD-E. It is a 4-channel microprocessor-based system that measures the voltage output of each QUAD element and does the math necessary to provide a measurement of the X and Y displacement of a laser beam or image. It is fast and can be used to track, align and/or measure movement in real time, with a resolution of just a few microns!

Our large area pyroelectric quadrant detectors provide unique advantages over other position sensing detectors like silicon quads or lateral effect photodiodes. They are fast, handle high peak power of pulsed lasers without saturation and respond to lasers across the spectrum, from UV to Far IR and even THz. The QUAD-E is intended for use with pulsed sources at up to 1000 Hz, while the QUAD-P is designed for CW and high repetition rate (quasi CW) sources. Both types of detectors can also be used as standalone units, in an analog mode, for incorporation into your own system application. We can provide a lemo pigtail cable for this purpose.

Gauges are also tricky when it comes to stretching, because you’re not stretching the same amount every time. For instance, 8g to 6g is a stretch of 1 millimeter. But when you stretch from 2g to 0g, that’s 2 millimeters — twice as a big of a jump!

The next size after 00g is 7/16". The sizes go up by 1 sixteenth of an inch from there, but they’re reduced fractions, so instead of 8/16", we just say 1/2".

We've developed a unique position calibration routine which allows you to calibrate our QUAD-4TRACK system when working with a uniformly round laser beam. It requires the use of a micrometer-driven linear stage (1-axis only). As you can see from the calibration screen on the left, the procedure involves zeroing the instrument, moving the QUAD probe to nine discrete positions (+2.000 to - 2.000 mm) and then capturing the QUAD readings. It then determines correction coefficients (last column) and applies them to the raw data to arrive at "corrected positions". The QUAD probe is now calibrated!

With body jewelry, gauges aren’t an exact standardized measurement. Depending on the brand or jewelry, one 0g pair of plugs may be slightly smaller or larger than another 0g pair.

Laser power detector for measurement up to 50 000 W that traps > 97 % of the incident light and handles high intensities of small beams.

QUAD-4TRACK includes powerful, stand alone, LabView software which is used to control the instrument, process the data, and display X and Y position. It also displays the energy or power of your source and repetition rate. The large graphic in this screen shows the position of the centroid of the beam and tracks its movement in real time. The software includes many handy features like: set boundary, zoom (2X to 128X), set resolution, data logging, and many more. The green line represents the tracking history.

In the measurement screen shown on the left, we are tracking the beam stability of a pulsed Nd:YLF laser at 10 Hz. The resolution was set at 0.001 nm, the boundary is at 20 µm (red circle), and the zoom feature is at 64X. The total energy is 108.5 µJ, the final position of the laser is at -8 µm in X and -8 µm in Y. The green tracking line shows the movement of the laser about the zero position over a few hundred pulses.

Back then, wire was often made thinner by pulling it through smaller and smaller holes. A thick wire might be pulled through one hole, while a thin wire might have to be pulled through a dozen times, getting thinner and thinner each time.

All of our jewelry is marked in both gauge size and in millimeters, so you’ll know exactly what size you’re getting. We also offer a lot of in-between sizes you won’t find elsewhere, like 1g (equal to 7mm).

The analog output of the QUAD-4TRACK provides voltage that is directly proportional to the pulse energy or laser power irradiating each QUAD element. When the four voltage outputs are equal, the beam is centered on the QUAD detector. This provides a very useful tool when setting up our QUAD probes with your source for optical alignment.

For these two reasons, it’s often a good idea to use millimeters instead of gauges and inches when stretching. (Plus, you don’t have to reduce fractions in millimeters!)
