ABSTRACT:
The output of a continuous wave modelocked Nd:YAG laser is first pulse compressed and then frequency doubled from infrared to green, to provide a new pumping source for a synchronously pumped dye laser. The disclosed apparatus and methods can achieve tunable subpicosecond pulses at relatively high average power, over 300 milliwatts. The 1064 nanometer output of the pulse compressor is frequency doubled to 532 nanometers so as to provide 3.5 picosecond pump pulses at 82 MHz and average power exceeding one watt. When this is used to pump a Rhodamine 6G dye laser, tunable pulses as short as 190 femtoseconds output can be obtained from the dye laser, with average power over 300 milliwatts. With the addition of a cavity dumper, tunable subpicosecond pulses of 80 kilowatt peak power have been generated.
