Tunable, High-Power, Subpicosecond Blue-Green Dye Laser System with a Two-Stage Dye Amplifier
نویسندگان
چکیده
A two-stage dye amplifier design has been developed to amplify tunable, blue-green, subpicosecond dye laser pulses which are generated from a hybrid synchronously modelocked dye oscillator directly (800 fs) or shorter to 200 fs by a fiber compressor stage. This system has achieved single pulse energies of 2 mJ, with an amplified spontaneous emission content of less than 0.1%. Using 40 mJ of the third-harmonic output of an Nd : YAG regenerative amplifier to pump the dye amplifier system, these pulse energies represent an energy extraction efficiency of 5%. The tunability, stability, and spatial and temporal quality of the output pulses from the system have also been characterized.

Tunable subpicosecond dye laser amplified at 1 kHz by a cavity - dumped , Q - switched , and mode - locked Nd : YAG laser
Tunable subpicosecond pulses are generated by synchronously pumping a dye laser with the pulse-compressed and frequency-doubled output of an acousto-optically mode-locked cw Nd:YAG laser. The pulses are amplified at a repetition rate of 1 kHz, using the frequency-doubled output of a cavity-dumped, acousto-optically mode-locked, Qswitched, cw pumped Nd:YAG laser. Amplified transform-limited puls...
متن کاملGeneration of tunable subpicosecond light pulses in the midinfrared between 4.5 and 11.5 microm.
Stable subpicosecond infrared pulses in the spectral region of 4.5-11.5 microm are generated by difference-frequency mixing in AgGaS(2). The system uses femtosecond pulses from a Ti:sapphire regenerative amplifier and from a tunable traveling-wave dye laser. The infrared pulses have a duration of 400 fs, an energy of more than 10 nJ, and a repetition rate of 1 kHz.

We demonstrate a new type of four-pass dye laser amplifier that can reduce the possibility of parasitic oscillation between optical components used in the amplifier. Pumping the amplifier with a 5.6-mJ Q-switched doubled Nd:YAG laser output, we obtain high-peak-power pulsed output of an incident cw narrow-bandwidth dye laser beam with a power gain greater than 2 x 10(6) . Subsequent amplificati...
