Thermal effects in solid-state laser materials are a critical issue for designing diode-pumped solid-state lasers, the temperature distribution with different pump beam transverse profiles by using finite element method on 3–5μm solid-state laser are give in this paper. Based on the theoretical analysis, the thermal focal length of Tm: YAP crystal "b" direction and "c" direction...
In this paper, a high power laser diode electrical derivative parameters test instrument is developed, the wavelength range of this instrument is between 400nm to 1300nm, the power range of this instrument is between 1W to 15W. The relationships between the device reliability and the electrical derivative parameters are discussed. Then the measurements of 20 high power 808nm AlGaAs/GaAs laser diodes...
Lifetime is a key parameter for electronic products using, and how to obtain the lifetime by using a short-term aging data has become a challenging issue. In this paper, a new aging data analysis method will be introduced, and three groups of aging data for high power laser diodes will be as a case to expound this method. The aging test time will be greatly decreased by using this method.
