Abstract
A laser apparatus and method are provided for generating optical pulses based on Q-switching controllable with a fast and reliable two-dimensional (2-D) spatial light modulator, such as a digital micro-mirror device (DMD). Temporal and spatial modulation may be applied to selectively control the Q-switching provided by the spatial light modulator. The apparatus and method may be optionally optimized with straightforward optical components to increase angular magnification of a beam incident on the spatial light modulator and thus effectively reduce the Q-switching time.
