Abstract:
Advantages of ZnGeP2 crystals over AgGaSe2 and GaSe have been demonstrated in the comparative experiment on second harmonic generation in a mini-TEA CO2 laser. The mean power of the second harmonic achieved was 0.22 W at the conversion efficiency of 6%. It follows from the obtained data that the fundamental physical properties of laminar GaSe crystals are masked by low cleavage. Doping of GaSe crystals with indium significantly improves the cleavage and makes them potentially most attractive crystals for doubling the frequency of CO2 lasers.
