    摘要： A CO2 laser reference oscillator (RO) can provide injection seeding to a Q-switched (QS) or Q-switched cavity dumped (QSCD) CO2 laser, where the output frequency of the RO laser is locked to the peak of the laser line by the use of appropriate electronics to dither one of the resonator mirrors of the reference oscillator. This injected radiation seeds the radiation building up within the Q-switched laser cavity, such that the oscillating frequency favors the wavelength of the injected radiation. An electronic feedback control circuit can be used to lock an axial mode of the Q-switched laser to line center. The change in build-up time of the pulses within the QS laser can be used to maintain cavity length at a value that enables oscillating at the peak of the same laser line that is injected into QS laser.

    摘要： An improved laser system includes a sealed-off, RF excited, diffusion cooled, high pressure, short pulsed, high peak power waveguide and slab CO2 laser that avoids problems typically associated with obtaining a diffused discharge at high gas pressures, without arcing and without corona, while maintaining the unsaturated gain and gas temperature experienced at low pressures and scaling to higher pressures. Such a system has a long operating life-time, and is capable of operation at high gas pressures to obtain relative fast rise and fall time pulses. The system emits relatively short pulse widths, with pulse energies up to and exceeding 30 mJ, with reasonably high pulse repetition rates. The system also has a low pulsed RF power duty cycle, thereby enabling the generation of high peak power pulses, as well as reasonable average power and reasonably high peak powers.
