Laser stabilized to a room temperature cavity with AlGaAs coatings reaching fractional frequency instability

Chun Yu Ma, Jialiang Yu, Steffen Sauer +6

We present a laser system referenced to a room-temperature ultrastable cavity employing crystalline AlGaAs coatings. We demonstrate a fractional frequency instability of $4.2 \time…
