ABSTRACT
We have designed, fabricated, and tested laser mirrors made entirely from porous silicon (PSi). PSi high reflectors and output couplers were designed for continuous-wave and mode-locked Ti:Sapphire lasers that were tuned between 730 nm and 940 nm. The mode-locked version of this laser produced 80 fs pulses at 85 MHz, parameters very similar to those observed with the commercial mirrors. We also made a PSi-dye laser by inserting a dye-filled cuvette between two PSi mirrors that was pumped from the side with a pulsed, frequency doubled, Nd:YAG laser. Lasers working with the PSi mirrors exhibited stable operation over time. © 2004 American Institute of Physics.
