Abstract

We present a 10 W average power saturable Bragg reflector (SBR) cw modelocked laser operating at 1064 nm. The laser produces 35 ps pulses at repetition rates between 75 MHz and 250 MHz. The laser gain material used is Nd:vanadate (Nd:YVO₄), which is pumped with 30 W from a fiber coupled diode bar operating at 808 nm. SBR modelocking provides a reliable and robust method of modelocking solid state lasers. It behaves like a high damage threshold solid state saturable absorber. The modelocking process is self- starting and requires no active cavity stabilization thus enabling turn-key operation. We present results on power stability, damage thresholds and beam quality taken over many hours of operation. In addition we present our results on efficient single pass second and third harmonic generation of this laser system using LBO and KTP.
