Temperature dependence of 914 nm stimulated emission cross section of diode end-pumped nd:yvo4

The thermal effect on stimulated emission cross section of 914 nm (R 2 →Z 5 ) emission of 4 F 3/2 → 4 I 9/2 transition in Nd:YVO 4 was investigated. The gain medium temperature was stabilized via thermoelectric cooler which controlled in the range of - 3 o C to 60 o C. T...
