Abstract

We demonstrate the high-power laser performance with a disordered $\mathrm{Nd}\text{:}\mathrm{Ca}\mathrm{Y}\mathrm{Al}{\mathrm{O}}_4$ crystal at a wavelength of about $1.08\mathrm{\mu m}$. Continuous-wave output power of $5.16\mathrm{W}$ is achieved with a laser diode as the pump source. For the first time to our knowledge, the passively Q-switched $\mathrm{Nd}\text{:}\mathrm{Ca}\mathrm{Y}\mathrm{Al}{\mathrm{O}}_4$ laser is obtained with the maximum average output power of $2.39\mathrm{W}$, shortest pulse width of $5.7\mathrm{ns}$, and highest peak power of $15.47\mathrm{kW}$. By spectral analysis, the $\mathrm{Nd}\text{:}\mathrm{Ca}\mathrm{Al}{\mathrm{O}}_4$ laser wavelength is centered at about $1.08\mathrm{\mu m}$. We propose that, by suitable tuning, the $\mathrm{Nd}\text{:}\mathrm{Ca}\mathrm{Y}\mathrm{Al}{\mathrm{O}}_4$ laser should be an excellent source for helium optical pumping.
