BRIEF COMMUNICATIONS: Single-frequency emission from a YAG:Nd3+ minilaser with wavelength tuning
Single-frequency lasing with an output power up to 8 mW was achieved using a neodymium-activated YAG crystal with a resonator length 3.5 cm. This crystal was pumped by a semiconductor laser. Mode selection and tuning of longitudinal modes within an interval of 1 cm−1 were performed by a thin-film Troitskoĭ selector.
