| Abstract: | High power semiconductor laser diode test system is built-up by using SG140-125AAA programming DC source,PCI-GPIB card,voltmeter,power meter,spectrometer,etc.Developed test software is based on LabVIEW platform.Through controlling the DC source and the trigger out and trigger in,on the pwer meter,carrying out test instruments synchronization and rapidly scanning test(about 300 ms per test point) with high accuracy,the system has obviously higher test speed than that the test methods with separately operating instruments.It can realized the sweep test of the kilowatt semiconductor laser diode parameters such as laser power,diode voltage,photoelectric conversion efficiency,threshold current and spectrum parameters.The test system is with high accuracy,fast sweep and convenient control interface.The results are visua and comprehensive. |
