We report widely tunable infrared and self-frequency-doubled operation in ytterbium-doped yttrium aluminum borate (Yb:YAB). In the infrared, tuning has been obtained between 1016 and 1090 nm and also near 1125 nm. A tuning range at the 1-W level of 55 nm has been obtained. As a self-frequency-doubled laser, green output powers of 65 mW at 510 nm and over 450 mW at 530 nm have been demonstrated with a maximum diode-to-green conversion efficiency of 5%. Yb:YAB has been shown to cover the wavelengths of the copper-vapor (510 nm), argon-ion (514 nm), doubled Nd:YAG (532 nm), green HeNe (543 nm), and the doubled Yb:Sr5(VO4)3F laser in the visible (∼565 nm).
