…ultra-high vacuum conditions and extremely low laser noise. All four of these programs utilize Coherent Mephisto lasers as first stage oscillators in their high-stability custom laser systems. Mephisto lasers were chosen in large part because independent studies have previously confirmed that these…

…configuration, similar to the Mephisto MOPA, and to use this to injection lock a high-power ring oscillator. Independent research has previously shown that the minimum noise increases by up to three orders of magnitude when a lownoise NPRO-type laser like Mephisto is boosted to the 200 watt range…
