Abstract
A continuously-pumped, repetitively-pulsed, Q-switched laser resonator includes two different gain-media which lase at about the same wavelength. By separately and variably pumping the different gain-media, the laser resonator can efficiently generate output radiation having parameters which stay constant over a much wider range of pulse-repetition frequency than would be possible were either one of the gain-media solely deployed in the resonator. In one embodiment, the laser resonator includes an arrangement for providing near real-time compensation for variations in thermal-lensing in the gain-media resulting from variations in pump-power or pulse-repetition frequency.
