Solid-state tunable laser with a forsterite converter

The energy efficiency of a forsterite laser was investigated. Calculations show that the use of real components limits the efficiency to ~10%. Some ways of optimising the parameters of such a laser are suggested. The calculated results are on the whole in agreement with the experimental data, including those obtained by other authors. A description is given of the first all-solid forsterite laser and ways of improving it further are proposed.
