808nm high power diode lasers  which is rapidly maturing technology technically and commercially since the introduction in 1999 of complete kilowatt-scale diode laser systems  have important applications in the fields of industry and pumping solid-state lasers (DPSSL). High power and high power conversion efficiency are extremely important in diode lasers  and they could lead to new applications where space  weight and electrical power are critical. High efficiency devices generate less waste heat  which means less strain on the cooling system and more tolerance to thermal conductivity variation  a lower junction temperature and longer lifetimes. Diode lasers with Al-free materials have superior power conversion efficiency compared with conventional AlGaAs/GaAs devices because of their lower differential series resistance and higher thermal conductivity. 808nm GaAsP/GalnP broad-waveguide emitting diode laser bars with 1mm cavity length have been fabricated. The peak power can reach to 100.9W at 106.5A at quasicontinuous wave operation (200s  1000Hz). The maximum power conversion efficiency is 57.38%. Based on these high power laser bars  we fabricate a 1 3 arrays  the maximum power is 64.3 W in continuous wave mode when the current is 25.0A. And the threshold current is 5.9A  the slope efficiency is 3.37 W/A. 2008 SPIE.

According to Generic Reliability Assurance Requirements for Passive Optical Components GR-1221-CORE (Issue 2  January 1999)  reliability determination test of different kinds of passive optical components which using in uncontrolled environments is taken. The test condition of High Temperature Storage Test (Dry Test) and Damp Test is in below sheet. Except for humidity condition  all is same. In order to save test time and cost  after a sires of contrast tests  the replacement of Dry Heat is discussed. Controlling the Failure mechanism of dry heat and damp heat of passive optical components  the contrast test of dry heat and damp heat for passive optical components (include DWDM  CWDM  Coupler  Isolator  mini Isolator) is taken. The test result of isolator is listed. Telcordia test not only test the reliability of the passive optical components  but also test the patience of the experimenter. The cost of Telcordia test in money  manpower and material resources  especially in time is heavy burden for the company. After a series of tests  we can find that Damp heat could factually test the reliability of passive optical components  and equipment manufacturer in accord with component manufacture could omit the dry heat test if damp heat test is taken first and passed.
