DPSSL-50

dpsslDiode-pumped solid-state lasers, produced by Optosystems LTD., are high-efficiency, reliable, acousto-optic Q-switch Nd:YAG lasers. Using diode pump allows to increase the efficiency, to simplify the design of laser systems, to improve the frequency and temporal stability of the laser output. Full electro-optical efficiency of diode-pumped solid-state laser is high as 10 %. Low intensity noise of diode lasers provide high stability of the laser output (RMS < 2%). The diode-pumped solid-state lasers do not require constant maintenance and its life-time is up to 10,000 hours.      In DPSSL series transverse pumping scheme of the active medium rod is used . The special geometry of the optical cavity allows for effective single-mode operation with a beam divergence close to the diffraction limit . Pulse mode is implemented by means of acousto-optic Q-switch cavity. In a DPSSL series model with intra- cavity conversion in the visible region of the spectrum is present. The high pulse energy and high average output power open a great opportunities of applications in micro-machining of different materials. The laser head is compact extremely rugged allowing maintenance-free operation.       Laser head delivered with a control and cooling units with dimensions 4U and 6U respectively , with mounting system in a standard 19 -inch rack. High performance makes these lasers an ideal tool in a variety of technological applications .       “Optosystems” LTD. develops and produces diode-pumped solid-state lasers for special applications and scientific investigations according to customer technical specifications.
