Paper Abstract

We describe a passively mode-locked, diode-pumped Nd:YAG laser that is used for frequency-conversion applications. The laser is based on a Direct-coupled Pump gain element and saturable Bragg reflector. The laser produces a 20-ps pulse with a 100-MHz repetition rate in a compact commercial package. It has typically <0.2% amplitude noise and diffraction-limited output beam. The average power is typically 7-8 W, and peak power is 4 kW which makes it well-suited for efficient frequency conversion. Using 2 stages of LBO for cascaded second-harmonic and sum-frequency generation, we have obtained >1 W at 355 nm. In addition, we have generated super-continuum output in the visible and infrared from micro-structured nonlinear fiber with pumping both at 1064 nm and 532 nm. Current applications for this laser, primarily in the ultraviolet, include flow cytometry, stereolithography, and semiconductor inspection.
