Hz-Level Rack Mounted Laser System

Hz-Level Rack Mounted Laser System

SLS-INT-1550-200-1

Obtain <1 Hz at the push of a bu_ on—less than 3 × 10^-15fractional deviation！

Our fully integrated cavity-stabilized laser system has been engineered to maximize performance and convenience in a compact footprint, combining high stability and ease of use.

UNCOMPROMISED PERFORMANCE

Everything needed to stabilize your laser has been incorporated into a convenient 19-inch, 6U rackmount box. This self-contained system includes a high-fi nesse Fabry-Perot cavity, temperature-controlled vacuum housing, vacuum pump, laser source, optics, and control electronics. Designed for portability and performance, it maintains the frequency stability for which our products are known: the frequency noise spectral density of 1 Hz/_Hz is ideal for applications such as microwave generation and laser radar.

INTELLIGENT DESIGN FOR EASE OF USE

Once the laser has been tuned to be coincident with the cavity frequency, a push-bu_ on lock function engages the loop fi lter to stabilize the laser. An intuitive, integrated touch screen allows control of laser current, laser temperature, loop fi lter parameters, as well as displaying the necessary diagnostics, including cavity temperature, refl ected and transmi_ ed power from the cavity, and vacuum parameters. Analog outputs are provided for transmi_ ed and refl ected photodetectors, error signal, and synchronous frequency ramp signal.

Decades of laser stabilization experience have gone into this optimally

engineered system. With minimal user maintenance, our systems give

you the frequency you need — guaranteed.
