Abstract: We report in the present paper the Yb3+-doped Y2Ca3B4O12 diode-pumped laser operation in both continuous-wave (cw) and passively Q-switched modes. The differential slopes of the cw output power are in the 22%–40% range under different experimental conditions. Continuous tuning of the laser wavelength is obtained in the 1020–1057 nm range, in agreement with the broad emission spectra. In pulsed regime the repetition rate occurs up to 1.6 kHz and pulse energies of 30–75 μJ with about 40 ns duration are obtained. [ABSTRACT FROM AUTHOR]
