Abstract
We report an intra-cavity frequency doubled diamond Raman laser
operating at 607 nm. A z-fold cavity design was configured to prevent
back reflections into the fiber amplifier, which avoided the use of
isolators in the pump beam path. A maximum output power of 60 W was
generated in two output beams at an optical conversion efficiency of
28% from the 1045 nm pump. A maximum single-beam output power of 40 W
was obtained using a highly reflecting end mirror for the visible.
Output power and single frequency stability are negatively impacted by
an increasing role of stimulated Brillouin scattering at output powers
above 10 W.
