Abstract
We present a new setup for efficient blue light generation with two passively locked optical resonators. The driving laser is based on a broad area laser diode (BAL) in an external cavity. The laser emission is stabilized by means of a holographic diffraction grating in a Littrow arrangement. With a special off-axis design of the external cavity the diode laser provides more than 450 mW diffraction limited and narrow bandwidth emission at 976 nm [1].
