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 1.4W primary (diode) pump power and 8.5W yielded 205mW idler.

Semiconductor disk lasers are diode-pumped solid-state lasers offering broad spectral coverage. An approach to thermal management that is similarly adaptable is thus required: finite element analysis shows that intracavity diamond heatspreaders are such an approach.

Finite-element analysis is used to explore the practicalities and scaling potential of heatspreaders in vertical-external-cavity surface-emitting lasers. Thermal lensing and its implications for quasi-monolithic microchip geometries are emphasised.
