Abstract

A mode-locked Ti:sapphire regenerative amplifier system pumped with a single argon ion laser produces μJ energy 100 femtosecond pulses of 800 nm wavelength at 250 kHz repetition rate. Pumping a Type II BaB₂O₄ (BBO) optical parametric amplifiers (OPA) with this output generates 500 nJ infrared pulses and continuous tuning from 1.1 μm to beyond 2.5 μm. Difference frequency generation of the signal idler output from this OPA source in AgGaS₂ produces 60 nJ mid infrared pulses and continuous tuning from 2.4 μm to beyond 12 μm
