Optical Parametric Oscillator

optical parametric oscillator implemented on BBO crystals using electrodynamic drive. Pump laser - Yag:Nd+3 on λ =1,064 micrometers Second harmonic generator - он LBO crystal with thermo-stabilization at T=423.2 K. λ =0,532 micrometers third harmonic generator - birefringent nonlinear crystal DKDP λ =0,355 micrometers actualy this is my graduation work :)
