Q-SWITCHED CAVITY DUMPED CO2 LASER FOR MATERIAL PROCESSING |
摘要 |
This disclosure discusses techniques for obtaining wavelength selected simultaneously super pulsed Q-switched and cavity dumped laser pulses utilizing high optical damage threshold electro-optic modulators, maintaining a zero DC voltage bias on the CdTe electro-optic modulator (142) (EOM) so as to minimize polarization variations depending on the location of the laser beam (402) propagating through the CdSe EOM crystal (142), as well as the addition of one or more laser amplifiers in a compact package and the use of simultaneous gain switched, Q-switched and cavity dumped operation of CO2 lasers for generating shorter pulses and higher peak power for the hole drilling, engraving and perforation applications. |
