title: Tunable narrow linewidth AlGaInP semiconductor disk laser for Sr atom cooling applications.
abstract: We report a frequency-stabilized semiconductor disk laser based on AlGaInP and operating at 689 nm, a wavelength of interest for atomic clocks based on strontium atoms. With a gain structure designed for emission at around 690 nm, more than 100 mW of output power are generated in single-frequency operation. We show that the source can be tuned over 8 nm with pm precision. By servo-locking the frequency to the side of fringe of a reference cavity, we demonstrate rms frequency noise of 5.2 kHz.
