Abstract:

The change in the absorption efficiency of laser diode emission in the gain medium of Nd³⁺:YAG lasers is considered for a temperature shift of the pump spectrum by 25–30 nm. It is shown that, for a typical width of the emission spectrum of modern linear laser diode arrays, the minimum efficiency can be significantly increased if the pump spectrum consists of not one but two spectral peaks of different intensities. The increase in the number of peaks to more than two does not lead to any significant improvement in efficiency.
