We demonstrate the high-power laser performance with a disordered Nd : Ca Y Al O 4 crystal at a wavelength of about 1.08 μm . Continuous-wave output power of 5.16 W is achieved with a laser diode as the pump source. For the first time to our knowledge, the passively Q-switched Nd : Ca Y Al O 4 laser is obtained with the maximum average output power of 2.39 W , shortest pulse width of 5.7 ns , and highest peak power of 15.47 kW . By spectral analysis, the Nd : Ca Al O 4 laser wavelength is centered at about 1.08 μm . We propose that, by suitable tuning, the Nd : Ca Y Al O 4 laser should be an excellent source for helium optical pumping.
