Mephisto lasers push the boundaries of what continuous-wave lasers can do. They offer the lowest noise and the narrowest linewidths available—perfect for high-precision experiments and demanding OEM systems. With a linewidth as narrow as 3 kHz, these lasers deliver unmatched interferometer resolution. Their ultra-low RIN (Relative Intensity Noise) ensures pristine data quality, even in the most sensitive measurements. Built around a monolithic ring oscillator, they combine stability with ultra-fine tuning capabilities. Whether you’re working on cutting-edge research or developing next-generation instrumentation, Mephisto lasers set a new standard of excellence.
These lasers are engineered for applications where precision is everything. Their performance is rooted in advanced design and manufacturing:
Harness the same level of performance that powers the most sensitive scientific experiments. Mephisto lasers are more than tools—they’re partners in discovery. With their unmatched noise performance and tunability, they open new doors for your most demanding applications.
