TEMPERATURE CONTROL DEVICE AND METHOD FOR A HIGH POWER LASER MODULE CAPABLE OF INCREASING THE EFFICIENCY OF A LASER DRIVER DEVICE

摘要

PURPOSE: A temperature control device and method for a high power laser module are provided to obtain an optimized output and wavelength by controlling a temperature according to temperature characteristics of a high power laser module.;CONSTITUTION: An input unit(10) receives a start command and a reference temperature value. A temperature detector(20) detects a temperature in a laser diode. A controller(30) compares the detected temperature and the reference temperature. The controller outputs a temperature control signal. A temperature controller(40) constantly maintains the temperature of a laser diode module. The temperature controller includes an H-bridge circuit(41) and a thermoelectric element unit(42).;COPYRIGHT KIPO 2013;[Reference numerals] (10) Input unit; (20) Temperature detector; (30) Controller; (41) H-bridge circuit; (42) Thermoelectric element unit
