The diode-pumped multi-wavelength continuous-wave laser operation of the disordered Yb:Ca3Gd2(BO3)4 crystal was firstly investigated in this paper. The simultaneous emission wavelengths varied from 2 to 5 in the range from 1045.4 to 1063.6 nm with the change of the absorbed pump power and crystal length. An output power of 1.4 W was obtained with four-wavelength emission, corresponding to an optical–optical slope efficiency of 23.7%. Five-wavelength emission at 1049.4, 1051.3, 1053.4, 1055.6 and 1057.4 nm was realized under the output power of 1.0 W. The absorption behavior of Yb:Ca3Gd2(BO3)4 have also been measured.
► The continuous-wave laser operation of the disordered Yb:CGB crystal is firstly investigated. ► Five-wavelength emission is realized. ► The number of the emission wavelengths depends on the absorbed pump power level and crystal length. ► The absorption behavior is measured.
