Abstract
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.
