We describe a new source of continuous-wave (cw), single-frequency blue radiation tunable across 425-489 nm based on internal second harmonic generation of a cw singly-resonant optical parametric oscillator (SRO) pumped in the green. Using a 30-mm MgO:sPPLT as the SRO gain material and a 5-mm BiB3O6 crystal for doubling, we generate 450 mW of cw blue power with a linewidth of 8.5 MHz and a TEMoo profile. The device also generate a single-frequency signal output of ~100 mW across 850-978 nm and up to 2.6 W of idler power in the 1167-1422 nm spectral range.
