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...

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...
