Getting To Know LBO
Getting To Know LBO

Lithium Triborate, LiB3O5, or LBO-- all the same to me, but let's be friends, just call me LBO. I am an outstanding crystal for nonlinear optics, the best of my type. But why am I special, so special? It probably has something to do with the lithium. And, GAMDAN Optics has the best performing LBOs, period.

INTERFEROMETRY - FRINGES AND PHASES
INTERFEROMETRY - FRINGES AND PHASES

Before light sources with considerable coherence length were available (think lasers), opticians formed fringe patterns using a test plate, also known as an optical flat.  Spherical test plates also exist, to check the surface of lenses, or curved mirrors.  These test plates could be placed in close proximity to each other, so common light sources could be used.

WHAT IS WAVEFRONT DISTORTION?
WHAT IS WAVEFRONT DISTORTION?

A perfectly generated wave may be plano or spherical.  What happens to it as it travels may alter that perfect shape.  This circumstance is called wavefront distortion. 

Tight control of crystal growth, sophisticated selection of material, near compulsive attention to detail in manufacturing and polishing combine with discriminating inspection practices to ensure that GAMDAN Optics products are free of transmissive wavefront errors.

CONTAMINATION ON ULTRAVIOLET (UV) OPTICS
CONTAMINATION ON ULTRAVIOLET (UV) OPTICS

Contamination can find its way onto all types of optics.  UV light is generally more likely to break molecular bonds and cause damage than visible or infrared light.   Contamination can make a good optic appear to have a low threshold for laser induced damage.   Here we’ll explain a few types of contamination, and we’ll show what can be done to prevent contamination on UV optics.

Estimates of Second Harmonic Generation (SHG) Efficiency
Estimates of Second Harmonic Generation (SHG) Efficiency

Can the second harmonic generation be done efficiently with the right amount of peak power?  In this article we will analyze what happens with lower peak power.  For example, what if we run the same laser continuously (CW), so the average power might still be one Watt, but the peak power is now also now only one Watt.  Can we efficiently generate the second harmonic of that CW beam?  Read more and explore SGH with us…
