Infrared and visible absorption and fluorescence spectra of the novel laser crystal Yb:Ca4YB3O10 (Yb:YCOB) were recorded and spectral parameters were calculated. Infrared laser output powers of 446mW were realized from a 1.86 mm thick Yb:YCOB crystal pumped by a 1.6W fiber-coupled 976nm diode. with slope efficiency of 73% and threshold of 55mW. Self-frequency-doubled green light was also observed.
