We report a mid-infrared femtosecond OPO based on CdSiP2 tunable across 6786–7069 nm, generating record power of 110-mW at 7μm, with passive power and wavelength stability below 3% rms (1-hour) and 0.1% rms (15-min), respectively.
We report a compact, stable, 79.5-MHz, Yb-fiber-based, picosecond UV source generating 1.2-W of power at 355 nm with a stability better than 0.4% rms over 3 hours, and pointing stability <45 μrad in good spatial-beam-quality.
Nonlinear frequency conversion has been proven to be an attractive alternative to access spectral regions that are inaccessible to conventional laser sources. Still, the high-power, continuous-wave (cw) ultraviolet (UV) generation, based on frequency conversion processes, has been challenging due to the short-wavelength transparency cut-off and low nonlinearity of the available nonlinear materials...
We demonstrate a tunable picosecond source providing up to 3.5 W over 752–860 nm, with a power stability of 1.6% rms over 14 hours using intracavity frequency-doubling in optical-parametric-oscillator synchronously pumped by a Yb-fiber laser.
Continuous-wave (cw) singly-resonant optical parametric oscillators (SROs) represent versatile sources of widely tunable, high-power, single-frequency radiation in spectral regions inaccessible to lasers. Pumped at 1.064 mum, PPLN cw SROs can cover the 1-5 mum spectral range, but access to wavelengths <1mum is precluded by photorefractive damage in PPLN. Due to its large photorefractive damage...
