| Abstract: | The effect of enhanced luminescence in polished rods on the generation threshold and power as determined by rod length, on reflectances of the external mirrors, and on the interior loss factor is investigated. It is shown that increasing the length of the rod can cut off generation, and that the threshold with ordinary rod lengths is several times higher than that computed without allowance for enhanced luminescence. Sample calculations are carried out for ruby and neodymium glass rods.We are grateful to B.I. Stepanov for his interest and useful comments on the present study. |
