Abstract
Thermoelectric cooler (TEC) system is important in order to stabilize the output of Diode Pumped Solid State Laser (DPSS) laser. The aim of this study is to diagnose the performance of TEC in DPSS system. High power diode laser (DL) driver was utilized as a pumping source. The current of the driver was verified and the temperature of the DL and KTP were measured. The threshold current for DPSS laser was obtained at 7 A. The temperature of diode laser was found drastically increase before threshold current. Beyond that point the temperature remained constant at 25.4°C. However in KTP crystal, three phases produced before achieving the same constant temperature of DL. Thus TEC was effectively controlled the temperature of KTP at ambient temperature of 25.4°C after diode laser was pumped with current greater than 18 A.
