We report distinct laser performance of Yb:Gd Ca 4 O ( BO 3 ) 3 crystals cut along different principal optical axes using an unpolarized diode pump. The continuous-wave (cw) laser oscillation generated with y-cut crystal is polarized either with E x or with E z depending on the output coupling (T) utilized; a specific T = 3 % leads to a special situation in which the two orthogonal polarization states coexist oscillating at different wavelengths. The laser oscillation achieved with x- and z-cut crystals is also polarized, but with a fixed polarization of E z and E x , respectively. The most efficient laser operation is obtained with the y-cut crystal, generating a cw output power of 7.35 W at 1083 1085 nm with an optical-to-optical efficiency of 63%, the slope efficiency being as high as 84%.
