An enclosure surrounding the optical component can be connected with a vapor source. The vapor source can provide a vapor to the enclosure with a vapor level from 500 ppm to 15000 ppm. The concentration of vapor in the enclosure can increase the lifespan of the optical component in the enclosure.

Vapor as a protectant and lifetime extender in optical systems

The present invention provides an apparatus for mechanically stabilizing tunable lasers by mechanically grounding laser components. Lasers stabilized using mechanical grounding of the laser components exhibit phase synchronous tuning, reduced mode hop and increased wavelength stability across the entire tuning range. Additionally, lasers stabilized using mechanical grounding exhibit improved resistance to thermal and physical shock. The robust compact design of mechanically grounded lasers makes them suitable for a broad range of applications including optical signal generators and optical multimeters.

Mechanically grounded tunable laser

Disclosed is an external cavity diode laser system that includes a dispersion unit; a gain element producing coherent light incident upon the dispersion unit; and the dispersion unit dispersing the incident coherent light into dispersed light, the dispersed light comprising a reflected diffraction beam and at least one of angularly-separated source spontaneous emission or angularly-separated amplified spontaneous emission; a guiding dispersion unit that guides the dispersed light diffracted upon it from the dispersion unit while maintaining an angular separation between the reflected diffraction beam and at least one of angularly-separated source spontaneous emission or angularly-separated amplified spontaneous emission; and a physical filtering device that physically filters the reflected diffraction beam from the spatially separated at least one of angularly-separated source spontaneous emission or angularly-separated amplified spontaneous emission guided to the physical filtering device by the guiding unit to produce a low-noise laser beam. Also disclosed are methods relating to producing low-noise laser beams.

Continuously grating-tuned external cavity laser with automatic suppression of source spontaneous emission and amplified spontaneous emission

The present invention provides an apparatus for passively stabilizing the optical pathlength in tunable lasers. Lasers stabilized using the passive stabilization apparatus exhibit reduced mode hop and increased wavelength stability during temperature variations of the laser or surrounding environment. The stabilization makes the laser suitable for a broad range of applications including: optical signal generators and optical multimeters.
