Abstract:
A wavelength-stabilized compact diode laser system
emitting at 671 nm mounted on a microoptical bench with the dimensions
of 13mm x 4mm is presented. A reflecting Bragg grating
was aligned on the rear side of a broad-area gain medium for wavelength
stabilization at 671 nm. A maximum output power of 1.5W
was obtained together with a spectral width of 40 pm (full-width
at half-maximum). At 1.0 W, a center wavelength stability below
20 pm over 5 h was determined. With these features, the devices
are well-suited for spectroscopic applications.
