FemtosecondSynchronously Pumped Parametric Oscillator >

The Spectra-Physics Opal > is asynchronously pumped parametric oscillator (SPPO) that delivers tunable femtosecond pulses from 1.1 to 2.25 microns. Opal enhances the versatility of the Tsunami > The Opal Advantage. Wide continuous spectral coverage:synchronized signal and idler outputs deliver wavelengths from1.1to 2.25 m > ՙ ultrafast Ti:sapphire laser byextending its output into the infrared. In addition, Opal also provides frequency- doubled access to the missingӔ visible region not accessible by Ti:sapphire alone. Opal features all solid-state constructionfor maximum reliability and ruggedness....

Opal cavity layout (includes prisms when using short wavelength mirror set). Millennia and TsunamiThe Ultimate Pump Combination To achieve optimum performance, asynchronously pumped oscillator requires a pump source with high stability, high peak power, and excellent beam characteristics, including beam pointing stability. It must also deliver a constant pulse repetition rate to minimize cavity length adjustments. In the case of a synchronously pumped parametric oscillator such as Opal, the non-linear effect is very short lived, and the pump laser requirements are even tighter. The Spectra-Physics...
