Abstract:
We report the results of experiments on frequency conversion of a Ho : YAG laser beam (wavelength λ ~ 2.1 mm) 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 mm) reaches 55%, while for the far-IR range (λ = 8 – 8.2 mm) it turns out to be 10.5%.
Keywords:
Ho : YAG laser, nonlinear conversion, second-harmonic generator, optical parametric oscillator.
