Litron is one of the few laser manufacturers to offer Nd:YAG lasers with true TEM00 beam quality as standard. Some manufacturers claim to offer lasers with TEM00 output but a closer look will show that that is not always the case.
Lasers for Holographic and Interferometric Techniques
Pulsed Nd:YAG lasers running on a single longitudinal mode (SLM) have been around for over twenty years. Their long temporal coherence length of typically 2-3m make them very well suited for many applications.
Comparison of Beam Divergence, Beam Diameter and M2
Why the Aperture – Divergence Product Doesn’t Tell the Whole Story.
A true measure of the quality of a laser beam is the parameter known as M2, also referred to as a number of ‘times diffraction limited’.
The advantages of a twin rod, birefringence compensated architecture in high average power pulsed Nd:YAG lasers: much improved spatial profile, extraction efficiency and harmonic conversion efficiency.
