| Abstract | ||
| In this work, an expermental study on wavelength tunning for diode laser adopting temperature behavior varition process is carried out .Temperature effect on the characteristics of a stripe Double Heterostructure CW (GaAlAs) diode laser is shown . For the purpose of optimum operation a collection of important information has been extracted regarding threshold current and senstivity of the laser diode as a function of temperature. It was found that the increasing in temperature (10-40)ºC resulting in an increasing in the values of forward current and the output power of the laser diode. the threshould current shows a drop in the value(48-61)mA, and increase in the differential or slope efficienecy (0.1-0.25)mW/mA | ||
