Mephisto


Delivering the lowest noise and narrowest linewidths of any available CW lasers, the Mephisto family are ideal for laboratory research or OEM instrumentation.

Mephisto lasers are at the heart of every gravitational-wave observatory to date. Harness this same performance excellence in your application. Based on a non-planar ring oscillator (NPRO) they provide both temperature frequency tuning and fine pzt tuning.


Mephisto Family Summary

The lowest noise and ultimate stability (Mephisto/Mephisto S), high power (Mephisto MOPA), and visible output (Prometheus).
