Control of Superfluorescence for the Optical Parametric Chirped Pulse Amplifier Based on Fiber Laser
|
Abstract:
By using a novel double-pass optical parametric chirped pulse amplifier in a single nonlinear crystal,control of the superfluorescence was studied for the optical parametric chirped pulse amplifier based on fiber laser. Net saturated gain of 2×106 has been achieved and the superfluorescence is obviously decreased to less than 1% of the total output pulse energy when the signal is amplified to 2 mJ with rms fluctuations of less than 3% which is saturated after the amplifier. By this scheme, the superfluorescence is effectivly constrained and the stability of the signal is greatly increased.
