• SWITCHED YBYCA4O(BO3)(3) LASER
• CONTINUOUS-WAVE
• EFFICIENT

Efficient laser action was demonstrated in the long-wavelength emission sideband of Yb: YCa4O(BO3)(3) crystal by effectively suppressing lasing in the main emission band with specific mirror coatings. With an X-cut crystal, a maximum output power of 13.0 W at wavelengths around 1065 nm with E//Z was generated with an optical-to-optical efficiency of 45.1%; with a Z-cut crystal, the highest output power around 1085 nm with E//X amounted to 15.5 W, the optical-to-optical efficiency being 44.4%. The most efficient laser oscillation realized with Y-cut crystal consisted of two orthogonal polarization components, E//Z and E//X, that occurred in different wavelength regions centered at about 1065 and 1084 nm, producing a total output power of 15.0 W with an optical-to-optical efficiency of 46.3%.
