DIODE PUMPED LASER 487
Description
Unlike their lamp pumped counterparts, Diode Pumped Lasers use high efficiency, long life solid state diodes as their pump source. The diodes emit light precisely at the Nd:YAG pump band, unlike flash lamps, which emit light in a broad spectrum. The unused light in a lamp pumped laser generates extra heat in the laser rod which must be dissipated by the cooling system. This heat causes thermal effects in the laser rod, and results in a loss of beam quality.
Because the solid state diodes emit light which closely matches the pump band of the rod, minimal excess heat is generated, resulting in better beam quality. An additional benefit is lower power usage, and a significantly smaller cooler. The U.S. Laser Diode Pumped Laser head features a proprietary design utilizing close coupled side pumping for high efficiency and beam circularity, and requires no routine maintenance. The solid state diodes used are only the highest quality, aluminum-free type, and their life expectation is well in excess of 10,000 hours.
Because of the excellent beam quality, U.S.Laser Diode Pumped Lasers can generally be focused to smaller spot sizes, and are excellent lasers for use in laser marking and micro machining. When used in Q-switched mode, diode lasers generally have shorter pulse duration than their lamp pumped counterparts. In many applications a lower power diode pumped laser will do the same job as a higher powered lamp pumped laser. Earlier U.S. Laser systems with lamp pumped lasers can easily be retrofitted with newer style diode pumped lasers.
