Frequency Doubling at 1.315 Micrometers

Abstract

Using lithium iodate crystals, second harmonic generation of chemical oxygen iodine laser (COIL) light (gamma = 1.315 mircometer) has been demonstrated for the first time. Both a photolytic iodine laser and a COIL were used. For the photolytic iodine laser, 320 mW of red output in 40 microsecond pulses was generated in an extracavity configuration at a conversion efficiency of 2.1 x 10 to the minus 5th power. With the COIL device, 60 mW of average second harmonic power was observed at an overall conversion efficiency of 1 percent when the crystal was placed intracavity. In both cases, experimental second harmonic powers were in good agreement with theoretical values. Keywords: Frequency doubling, Second harmonic generation, Intracavity, Extracavity, Lithium iodate, Chemical oxygen iodine laser, Photolytic iodine laser.
