Abstract

The high vacuum cleaving passivation characteristic on 980nm diode laser is presented. In this research, diode lasers are cleaved in high vacuum cleaving system, and then coated with thin ZnSe passivation layer in the front and the back facet. The function of the passivation layer is to protect diode lasers facet, and prevent impurity particles diffusing into the facet. Finally optical coatings are applied to the AR and HR facets of 5% and 98% respectively in the front and the back facets. The test results of diode lasers output power show that the output power with ZnSe passivation layer method is 9% higher than Si passivation layer, and 21% higher than that uncoated with passivation layer. The diode of uncoated passivation layer is failed when input current is 3.9A, and the diode coated with Si passivation layer is failed when input current is 4.6A, the final failed of the diode is coated ZnSe passivation layer. In conclusion, the method of coated ZnSe passivation layer in high vacuum cleaving system on the diode lasers facet can effectively prevent the catastrophic optical mirror damage, and increase the output power of diode lasers.
