We report generation of squeezed light at 860nm by using a periodically poled MgO:LiNbO3 crystal in a subthreshold optical parametric oscillator. At the pump power of 140mW we observed the squeezing level of −5.72 ±0.14dB.

We achieved 128mW of oscillation threshold of an optical parametric oscillator with a periodically poled MgO:LiNbO3 crystal and generated squeezed states of light whose squeezing level was -6.24 ±0.11dB at the pump power of 80mW.

We report on efficient generation of continuous-wave squeezed light and second harmonics with a periodically poled MgO:LiNbO(3) (PPMgLN) crystal which enables us to utilize the large nonlinear optical coefficient d(33). We achieved the squeezing level of -7.60+/-0.15 dB at 860 nm by utilizing a subthreshold optical parametric oscillator with a PPMgLN crystal. We also generated 400 mW of second harmonics at 430 nm from 570 mW of fundamental waves with 70% of conversion efficiency by using a PPMgLN crystal inside an external cavity.
