Scheme of intracavity frequency conversion with a single periodically poled crystal.
Experimental setup of the OPO based on quasiphasematched .
Average output power (solid circles) and conversion efficiency (open squares) in dependence of the incident pump power at . The OPO grating period , the SFG grating period .
Power of the sum frequency of the idler and pump radiation in dependence of cavity length detuning. The pump wavelength is , the grating periods are and .
Autocorrelation (a) and spectrum (b) of the SFG of the OPO idler and the pump radiation for maximum output power. Assuming a pulse shape, the pulse duration is . The spectral bandwidth is resulting in a time bandwidth product of 0.47.
