Summary
In Mephisto whitepaper #1, we explained how the combination of a monolithic non-planar
ring oscillator (NPRO) structure and active Noise Eater technology together make
Coherent Mephisto lasers the lowest noise source for demanding, narrow linewidth…

…the most demanding applications
Coherent's approach towards CW high-stability laser
sources is based on a non-planar ring oscillator (NPRO)
technology. Since its invention in Stanford University
[8], this technology has been recognized as the lowest
noise CW laser…

Mephisto MOPA Lasers

…25, 42 and 55 W are available. The higher power versions of the MOPA use an optical isolator to prevent damaging back-reflections into the Mephisto NPRO crystal. Because of the high pump and output powers of Mephisto MOPA, liquid cooling of the laser head is required. Due to the laser configuration,…

…instrumentation applications. Mephisto is a family of single frequency solid-state lasers based on Nd:YAG crystal in Non-Planar Ring Oscillator (NPRO) configuration. The intrinsic stability of the laser is further improved by our acclaimed Noise Eater (NE) technology which is now included with all…

…oscillator (NPRO) is still recognized as the lowest noise CW laser architecture. With a cavity based exclusively on a monolithic crystal rather than discrete optical elements, the NPRO can deliver linewidths <1 kHz because of its extremely low phase noise. The Coherent Mephisto's NPRO further lowers…

…contrast, a monolithic NPRO crystal
acts as both the gain medium and the cavity, which is defined by the crystal facets
(Figure 1).
One of the prerequisites for narrow linewidth in any laser is stable operation on a
single longitudinal mode. The NPRO naturally favors this…
