We present a novel ring resonator for second harmonic generation consisting of only two spherical mirrors and a refractive element. In our work we use periodically poled KTP as a nonlinear material for generating the second harmonic using an 808nm tapered grating stabilized external cavity laser as pump source.
With 286mW of fundamental 808nm radiation coupled into the resonator, we generate 130mW blue light at 404 nm, resulting in a power conversion efficiency of 45%
