Real-time Profiling for Focusing, M2, Divergence & Alignment
Author: Andrew MacGregor, Ph.D., VP Operations & Support and Rocco Dragone, M.Sc.Eng., VP Engineering
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.

Dispersive 1064nm Raman Spectrometer Family
Owing to technological improvements spurred on by the telecommunications boom of the last decade, Raman spectroscopy has become much more accessible to users in all fields. The combination of improved technology and the technique’s molecular sensitivity have led to a surge in Raman usage in a myriad of application areas, including pharmaceutical, biomedical, industrial, and forensic, among others. In all of these applications, however, there remains a struggle to extract useful Raman spectra...

The Benefits of Laser-Reflection Based Ultraprecision Active Alignment
Aligning and centering lenses for cementing or positioning in an optical system poses different challenges depending on the final precision requirements and the methods used during alignment. This paper details the benefits of laser-reflection-based ultraprecision active alignment and how it reduces the cost of optics and final assembly.

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.
