	%X Nowadays, quasi-continuous wave diode lasers are
used in a widespread variety of applications. Temperature effects in
these lasers can strongly influence their performance. In this paper,
the effects of temperature have been experimentally investigated on
different features of a 60W-QCW diode laser. The obtained results
indicate that the conversion efficiency and operation voltage of diode
laser decrease with the augmentation of the working temperature
associated with a redshift in the laser peak wavelength. Experimental
results show the emission peak wavelength of laser shifts 0.26 nm
and the conversion efficiency decreases 1.76 % with the increase of
temperature from 40 to 50 ̊C. Present study also shows the slope
efficiency decreases gradually at low temperatures and rapidly at
higher temperatures. Regarding the close dependence of the
mentioned parameters to the operating temperature, it is of great
importance to carefully control the working temperature of diode
laser, particularly for medical applications.
