Mephisto MOPA Lasers

Mephisto MOPA Lasers

…provides (up to 2 W). In these cases, the most effective approach is to use the exceptional beam properties of Mephisto to seed one or more cascaded amplification stages, resulting in a Master Oscillator Power Amplifier (MOPA) configuration. Mephisto MOPA laser incorporates a Mephisto S oscillator…

…a singlefrequency/wavelength stabilized laser source, ASE filters, a high-throughput beamsplitter, sample
collection optics, and multiple cascaded VHG notch filters. The filtered Raman signal is fed into a singlestage spectrometer for readout. (A schematic of the system is depicted on the left,…

WP1 MephistoNPRO Final.pdf

…Most commercial single frequency lasers used for narrow linewidth applications (Ti:Sapphire lasers, external cavity laser diodes and quantum cascade lasers) provide linewidth in the range 50 kHz to 1 MHz, which is usually adequate for many spectroscopic tasks. Nevertheless, some applications…
