Integrated 3 Hz Stabilized Laser Systems: SLS-INT-1550-200-3

We’ve put our many years of expertise into making this integrated rack-mount system as lightweight, low power, and easy to use as possible.

It is designed for low acceleration sensitivity using a proprietary cavity geometry symmetry requiring no additional vibration isolation, yet is capable of maintaining < 3 Hz linewidths with less than 100 kHz daily laser drift. This is our most robust, compact system for maximum portability and ease of use.

< 3 Hz linewidth in the most compact, portable footprint possible
