Real-time Profiling for Focusing, M2, Divergence & Alignment

Monday, January 14, 2013

Beam intensity profiling is an essential tool in many aspects of photonics. The precise intensity distribution in a focused laser beam is critical in many applications: flow cytometry, laser printing, medical lasers, and cutting lasers are just a few examples. Intensity profile measurements can characterize and improve a product or process, leading to substantial cost and time savings that can pay for the measurement instrument many times over. This white paper describes how the unique, patented, real-time multiple z-plane XYZTF capabilities of the BeamMap2 slit-scan profiler can speed and simplify laser assembly alignment.

Ultra-Narrowband Optical Bandpass Filters with Large Format and Improved Temperature Stability
Hard coated ultra-narrowband optical filters made using modern plasma processes offer much improved transmission, temperature stability and out of band blocking as compared to legacy soft coatings. These filters are used in optical systems as diverse as LIDAR (light detection and ranging), Doppler shift detection of plasma velocity, laser cleanup, chemical and gas sensing, as well as for cutting-edge astronomy and instrumentation applications.

Modifying Laser Beams: No Way Around It, So Here’s How
To apply a laser to an industrial process, medical therapy, or communications technology, it is usually necessary to modify the laser beam to achieve the desired results. Beam measurement tools make this possible. We will discuss how to match an appropriate laser beam profiling technique to a laser application, including building an aligned optical system, collimation and focusing, high power laser quality measurements, and proper attenuation techniques for making accurate laser measurements.

High Power All-In-Fibre Linearly Polarized Laser Using Chiral Grating-Based Polarizer
We present a linearly polarized all-in-fibre laser using a Chiral grating-based polarizer. This technology is potentially very promising for high power, compact linearly polarized all-in-fibre lasers. Comparing with other techniques, the laser structure is simpler and does not require external stabilization.
