External-cavity diode laser using a grazing-incidence diffraction grating.
An external cavity has been developed for use with commercial diode lasers. It uses a diffraction grating at grazing incidence for wavelength selection and output coupling. This configuration allows a GaAlAs diode laser to be tuned conveniently anywhere in a range greater than 20 nm. Also, the linewidth is reduced by a factor of more than 1000 from 40 MHz to less than 10 kHz. The new laser syst...
متن کاملExternal cavity multiwavelength superbroadband diode laser
Multiwavelength semiconductor laser source for dense wavelength division multiplexing (DWDM) applications based on a novel dispersive cavity is described. Multiline lasing on the basis of a single-diode laser chip and multi-stripe diode laser is analyzed theoretically and demonstrated experimentally. Simultaneous lasing across 80% of the FWHM of the luminescence bandwidth of the AlGaAs active m...
متن کاملElectronically tunable external-cavity laser diode.
We present a new concept for an electronically tunable diode laser. It is based on an external-cavity configuration with simultaneous feedback and intracavity spatial separation of the laser's spectral components. The electronical tunability is achieved by insertion of a liquid-crystal array as an electronically controlled aperture into the region of spatial separation of the spectral component...
متن کاملDual-wavelength actively mode-locked laser-diode array with an external grating-loaded cavity.
We report the generation of dual-wavelength picosecond pulses by use of a commercial laser-diode array. The laser cavity incorporated a folded dispersive delay line with a V-shaped double-stripe mirror. The spectral separation of the laser output at the two wavelengths can be tuned from 2 to 11 nm. The actively mode-locked pulse widths at the two wavelengths were both 29 ps. Cross-correlation a...
متن کاملTunable external-cavity diode laser at 650 nm based on a transmission diffraction grating.
A tunable external-cavity diode laser (ECDL) based on a transmission diffraction grating in a Littrow mount has been developed and characterized. A single-transverse-mode diode laser at 650 nm is used in an external-cavity configuration in which the transmission grating is used as a dispersive element to select the single longitudinal mode. The transmission diffraction grating is made with elec...
