We describe a continuous-wave optical parametric oscillator operated within a semiconductor disk laser, free of relaxation oscillations associated with neodymium-based systems. Parametric threshold occurred at 1.4 W primary (diode) pump power and 8.5 W yielded 205 mW idler.
The optically-pumped semiconductor disk laser is shown to be a practical low-noise pump source for Cr2+:chalcogenide lasers. Results on cw-pumping of a Cr2+:ZnSe and quasi-cw-pumping of a Cr2+:CdZnTe laser are presented.
