OPSL Advantages Whitepaper Series #3: No Mode Noise (“Green Noise”)

Download Whitepaper
The optically pumped semiconductor laser (OPSL) is a unique, patented technology that provides lower intrinsic noise than other continuous wave (CW) solid state lasers having UV or visible output, and is the only way to achieve true-CW output at 355 nm in a simple, cost-effective platform. The reason is the absence of mode noise due to the near-zero upper state lifetime of the OPSL gain medium.
