Portable Nd Oscillator-Amplifier Laser (NOAL) System
Technical Report
·
OSTI ID:6448492
A neodymium glass oscillator-amplifier laser (NOAL) system has been installed in an instrumentation trailer. The NOAL system consists of an oscillator and three amplifiers with the laser rods made from ED-2 or phosphate glass. The NOAL system can deliver 500 J (ED-2) or 700 J (phosphate), depending on which glass is used, in a 500 ..mu..s pulse. The lasing wavelength is either 1062.3 nm (ED-2) or 1053.5 nm (phosphate). With either type of glass the output beam diameter can be as large as 44 mm with a less than or equal to2.5-mrad beam divergence. The most reliable operation, which is obtained when only one of the two larger 45-mm-diameter amplifiers is used, delivers about 250 J (ED-2) or 450 J (phosphate) of energy per pulse. An extremely reliable NOAL system, capable of emitting about 800 J per pulse, could be assembled by placing two Lasermetrics oscillator-amplifier systems, each with a large-output Sandia amplifier, on the table in the trailer.
