Cw-operation, gain-switched, and passively <i>Q</i> -switched mode locking of Cr<sup>4+</sup>: YAG microchip lasers with output powers of several hundred milliwatts is demonstrated experimentally in the eye-safe region near 1.5µm . Requirements for cw mode locking of such lasers are investigated by numerical simulations.
