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.
