Abstract
Abstract
We report the results of experiments on frequency conversion of a Ho : YAG laser beam (wavelength λ ∼ 2.1 μm) into the near-, mid-, and far-IR regions, aimed at expanding the spectral composition of compact multispectral sources of coherent radiation. The experimentally found laser conversion efficiency into the second harmonic reaches 32 % and 54 % in the cw and repetitively pulsed regimes, respectively. The parametric conversion efficiency into the mid-IR range (λ = 3.5 – 5.0 μm) reaches 55 %, while for the far-IR range (λ = 8 – 8.2 μm) it turns out to be 10.5 %.
