CW Parametric Amplificati<strong>on</strong> in a Cavity<br />
Another soluti<strong>on</strong>: use a cw less<br />
intense pump laser <strong>and</strong> a cavity<br />
which is res<strong>on</strong>ant <strong>on</strong> the comm<strong>on</strong><br />
signal-idler mode <strong>and</strong> enhances the<br />
n<strong>on</strong>-linear interacti<strong>on</strong>.<br />
‘Optical Parametric Oscillator’, which<br />
can oscillate above a given<br />
threshold.<br />
(Output coupler R,T)<br />
- R=1 for all the mirrors, but the output coupler R<br />
- Losses L (absorpti<strong>on</strong>, interfaces,..)<br />
- Pump power normalized to the threshold :<br />
