Abstract: Laser pulses are selected from a group of closely spaced laser pulses with an optical modulator by adjusting pulse timing relative to an impingement interval. An adjusted pulse is moved from an impingement interval to a non-impingement interval and is blocked. The blocked laser source is stabilized by running nearly continuously. Pulse selection with multiple laser sources is achieved with a single acousto-optic modulator.
