Abstract

By using a CW mode-locked 532 nm laser to synchronously pump a crystalline Raman laser, we can generate output in the yellow-orange spectral region, suited to applications requiring low pulse energies and continuous pulse trains. We demonstrate a synchronously pumped Raman laser at 559 nm, pumped by a frequency-doubled mode-locked Nd:YVO₄ commercial laser. The generated CW mode-locked output had an overall (green-yellow) efficiency of 25.6%, and we observed a compression of the 10 ps pump pulses down to 3.2 ps at 559 nm. This compression was observed when the cavity length was slightly longer than for perfect synchronization.
