How Do High-Power Laser Systems Define Thickness Uniformity Requirements?

High-power laser applications demand exceptional control over the thickness of quartz plate to ensure safe and reliable operation. Engineers rely on quartz plates in laser technology because these materials offer high transmittance, strong corrosion resistance, and high temperature resistance. The uniformity of quartz plate thickness directly impacts the performance of core components of lasers, including laser resonator lenses and laser focusing lenses.

Stress-induced birefringence from thickness non-uniformity in high-power beams

Quartz plate thickness uniformity plays a crucial role in minimizing stress-induced birefringence in high-power laser beams.
