ABSTRACT:
A variable pulsewidth laser system is disclosed which employs an oscillating reflector to control the duration of laser pulses. In one embodiment, the oscillating mirror is swept (e.g., caused to swing back and forth) about an axis distinct from the optical axis, such that resonant conditions suitable for laser beam generation occur only at a particular location in the oscillating sweep path. By varying the scanning waveform, laser pulses of different durations can be generated.
