Ultimate Stability

With the same oscillator used in every LIGO instrument, our Mephisto MOPA products offer the lowest phase and intensity noise for all-optical atom trapping.

Simplified Tunable Ultrafast

Use our simplified tunable ultrafast lasers to create pairs of correlated photons for entanglement studies, e.g., by spontaneous parametric down-conversion.
