Abstract

We report external cavity Raman lasers using a 9.5-mm-long low-loss CVD diamond pumped by a 35 W q-switched Nd:YVO4 laser with approximately 22 ns pulses at 36 kHz pulse repetition frequency. Two systems were investigated. The first demonstrated first and second Stokes simultaneously with more than 14.5 W of combined optical power. For an output coupler optimized for second Stokes only output (1485 nm), 11.1 W at 38% conversion efficiency was obtained. This output power is comparable to the maximum output powers reported for competing pulsed eye-safe technologies such as optical parametric oscillators and Er:YAG lasers.
