Active electro-optic laser system for e.g. active imaging system, has optical gain medium pumped by optical pumping units, and optical switching device with control unit for units for activation of device in passing mode for preset period

摘要

The system has an optical gain medium (241) which is an absorbent with the wavelength of emission laser (10) and pumped by optical pumping units (242). An optical switching device (24) has a control unit (243) for the units (242) permitting activation of the device in a passing mode in a temporal window for a preset period. The device is activated at a preset instant after the start of transmission of illumination laser beam.
