METHOD, SYSTEM AND APPARATUS FOR AUTOMATICALLY DETERMINING OPERATING CONDITIONS OF PERIODICALLY POLED LITHIUM NIOBATE CRYSTAL IN LASER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method, system and apparatus for automatically determining operating conditions of a periodically poled lithium niobate crystal (PPLN) in a laser system.;SOLUTION: A system 100 comprise: a laser 101; a PPLN crystal 103 for receiving laser input from the laser; a temperature control device 105 for adjusting the temperature of the PPLN crystal; a temperature sensor 107 for monitoring the temperature of the PPLN crystal; and a computing device 109. While the PPLN crystal is receiving the laser input, the temperature of the PPLN crystal is changed using the temperature control device. The computing device monitors the temperature of the PPLN crystal and corresponding power of the temperature control device during the change of the temperature monitored using the temperature sensor. The computing device determines one or more of operating conditions of the temperature control device and an operating temperature of the PPLN crystal from a function of the power vs. the temperature.;COPYRIGHT: (C)2015,JPO&INPIT
