…replaced with a robust and versatile semiconductor chip. OPSL output power can be changed without affecting beam parameters due to the ultra-thin gain medium (i.e. no thermal lensing issues). In addition, the short upper-state lifetime of the OPS chip removes the “green noise” problem as seen with…

…test beam to probe the OPSL chip as it is simultaneously
irradiated by varying amounts of pump power. Specifically, a coherent single-mode laser beam
at 980 nm is split by the first beamsplitter so that part of its intensity is reflected off the OPSL
chip and part is reflected from a…
