Automated Laser Beam Propagation Analyzer supports 24/7 operation.

Press Release Summary:

Automated Laser Beam Propagation Analyzer supports 24/7 operation.

May 28, 2014 - Intended for use with pulsed or CW lasers from 266–1,300 nm, CCD camera-based M2-200s automatically measures beam quality in <2 min and supports continuous operation. This portable, ISO 11146-compliant system automatically measures M2, beam waist location and width, divergence, astigmatism, asymmetry ratio, and Rayleigh range for each axis. Input beam sizes can range from 0.5–10 mm, and manual mode allows for beams outside that range or wavelengths outside standard optical train.

North Logan, UT — Ophir Photonics Group, global leader in precision laser measurement equipment and a Newport Corporation brand, today announced the newest version of the M2-200s, the company's camera-based beam propagation analyzer. The M2-200s is an ISO 11146 compliant system that automatically measures laser beam quality in less than two minutes. It features a robust design that supports continuous, 24/7 operation. The latest version enhances the system's robust packaging with an all-new motor controller that decreases noise from motor movement by 30%.

The M2-200s is a compact, portable unit that features a CCD camera for use with pulsed or CW lasers, 266nm – 1300nm. The system automatically measures M2, beam waist location and width, divergence, astigmatism, asymmetry ratio, and the Rayleigh range for each axis. Input beam sizes can range from 0.5mm – 10mm. Manual mode is available for beams that are too large or too small, or for wavelengths outside the standard optical train.

"M2 is a common measure of the beam quality of a laser, allowing the laser to be tuned for optimum performance," stated Gary Wagner, General Manager (U.S.), Ophir Photonics. "The redesigned M2-200s, the world's top selling beam propagation system, provides high accuracy ISO 11145 compliant measurements and increased attention to durability and operational robustness for continuous use applications -- three shifts a day, seven days a week."

The M2-200s is fully ISO 11145 compliant, using a fixed position lens and moving detector. This allows measurement of M2 values whether the laser beam is diverging or converging. Non-ISO compliant instruments compromise results by using a moving lens and fixed detector.

The M2-200s supports both the 64-bit and 32-bit versions of Windows® 7, enhancing system configuration options and increasing processing speed. The software displays a 2D or 3D beam profile of the currently measured point in the beam propagation curve. After each run, the beam profile of any individual measured point can be observed. Outlying or anomalous points can be automatically or manually excluded from the curve fit calculations for more accurate results.

The M2-200s software is based on Spiricon's patented UltraCal™ calibration method and auto aperturing. This excludes noise beyond the wings of the laser beam and assures high accuracy measurements.
