【Abstract】 Lifetime of semiconductor laser diode(LD) module was researched.High-low temperature cycle lifetime of 1310 nm LD modules was studied by experiment under different simulation environmental conditions.A mathematical model of the cycle lifetime of laser diode was established.The result shows that cycle lifetime has index relation to the temperature difference of cycle and cycle speed.By testing the cycle lifetime of LDs under the high temperature difference and high cycle rate conditions,the cycle lifetime of LDs under the ordinary working conditions can be estimated.Reliability data of LD module is obtained.Quantity data is provided for technique designer.更多还原
