Efficient generation of the second harmonic of NH<sub>3</sub>laser radiation in CdGeAs<sub>2</sub>

Name: Work Video:
Duration: 3 min 30 s
Description: The second harmonic of radiation from a molecular NH3 laser was generated for the first time in CdGeAs2 single crystals. The internal efficiency of the frequency doubling reached 5% for radiation at the wavelength of 11.7 μ, when the efficiency of conversion of CO2 laser radiation power (used for direct optical pumping of the NH3 laser) into 6-μ radiation was highest.
