Integrated Frequency-Stabilized Single-Frequency Semiconductor Lasers Lasy 852
The integrated frequency-stabilized single-frequency semiconductor laser incorporates an internal frequency reference and locks its frequency for stable laser output. Its optical frequency is both stable and tunable, allowing the emitted wavelength to remain constant or scan according to application requirements. The Lasy series integrated frequency-stabilized sources from Spectra-line include an absolute frequency reference based on gas-reference spectra, ensuring stable laser-diode wavelength throughout its service life. For tuning to arbitrary wavelengths, the included interferometer reference provides delay-free tuning in continuous or stepped modes, with settling times within a few milliseconds. Applications include laser spectroscopy, atomic and molecular physics and quantum optics.
