【摘要】 用电导数技术测量了高功率半导体激光器及阵列激光器的m值,讨论了影响m值大小的因素及与器件质量的相关性。结果表明,m值是器件质量和可靠性的重要标志之一,对于同种器件,质量好的器件的m值一定在某范围之内。对取值范围进行了讨论。更多还原

【Abstract】 The values of m of some laser diodes and laser diode arrays were measured with electronic derivative measurement.The relationship between m and the quality of device is discussed.The results show that the value of m is an important parameter in indicating the quality and reliability of device.For a certain kind of device,m value of any one with a good quality certainly should be within some range and the range for different devices was discussed.更多还原
