Laser state - solid pumped by diode with the absorption of the pump light Improved

摘要

For solid-state laser pumped by a diode, measures to improve the absorption of the pump light in the crystal anisotropy, is the one proposed. Measures are proposed to reduce the dependence of the absorption of the pump light by the diode temperature and current of the diode is not only due to the fact that the detuning of the pump diode from the absorption line. These measures include sending twice pump radiation through the crystal, to put the crystal laser orientation where it is not intended to present the use and optimal absorption retarder.
