The Mephisto MOPA from Coherent is a Continous Wave Solid State Laser that operates at 1064 nm. This single-frequency laser is designed for demanding low noise scientific and OEM applications and its unique stability originates from the properties of widely recognized Non-Planar Ring Oscillator (NPRO). It provides unmatched optical properties such as ultra-narrow linewidth of 1 kHz and extremely low-intensity noise (-130 dB/Hz RIN), which is the result of an integrated Noise Eater (NE) technology. The laser is available at power levels of 8 W, 25 W, 42 W, and 55 W and has full control over emission frequency which can be adjusted by temperature and PZT. It is available in a module that measures 135 x 420 x 450 mm and is ideal for Atom trapping and cooling, optical lattices, gravitational wave studies, laser-based metrology, quantum optics, and phenomena, non-linear optics pump source (SHG, DFG, and OPO) and LIDAR applications.
