CANDELA photo-injector: the drive laser

In view of the future linear colliders, a bright photo-injector named CANDELA is being constructed at LAL Orsay. To illuminate the photo-cathode, a femtosecond Ti:sapphire laser has been developed. It consists of an oscillator that delivers a continuous train of femtosecond pulses at a repetition rate of 100 MHz. This train is then amplified in a regenerative amplifier pumped by a second harmonic Q-switched Nd:YAG laser. The status of the overall RF gun experiment is also mentioned. >
