LITRON LASERS
TECHNICAL NOTES

True TEM00 or Not?

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.

Different Resonator Options and why it’s important

Litron offers five distinct resonator configurations. This is more than any other manufacturer and this article sets out to help customers identify which one is best for their needs.

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’.

Motorised Harmonic Separation and Switching

One of many advanced features on the Litron LPY Series.
Motorised harmonic switching allows for remote switching between output wavelengths.

Twin Rod Birefringence Compensation Explained

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.
