Experimental study of the characteristics of high-power laser diode radiation in the above-threshold mode for degradation analysis
The angular dependence of the intensity and contrast of the radiation of laser diodes (LDs) with a CW power of 1.25 W has been investigated in the above-threshold mode. An original method for detecting fundame...
