【Abstract】 The dependence of the electrical derivative curve and its parameters on the reliability of 670 nm visible quantum well semiconductor lasers is discussed. It is shown that quality and reliability of the device can be evaluated by electrical derivative parameters ( m, h, b ). The experimental results show that electrical derivative measurement can be applied to screen visible semiconductor lasers instantaneousuly.更多还原
