LASER APPARATUS AND METHOD FOR GENERATING OPTICAL PULSES BASED ON Q-SWITCHING MODULATED WITH A 2-D SPATIAL LIGHT MODULATOR |
| 摘要 |
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. |

1. A laser apparatus for generating optical pulses comprising:
a laser cavity; a spatial light modulator comprising a two-dimensional array of pixels arranged to provide Q-switching at a pixel level in the laser cavity; and a controller connected to the spatial light modulator to temporally and spatially modulate the two-dimensional array of pixels to selectively control the Q-switching provided by the spatial light modulator. |
