Compact Mode-Hop Free Narrow Line Turnkey Laser System for Quantum Technology

In this Project OEwaves Inc. in collaboration with the UCLA trapped-ion quantum computing group proposes to develop extended-cavity ultra-stable diode laser systems that have the properties required for quantum computing and metrology. The system will be based on a semiconductor laser locked to a monolithic microcavity (a whispering gallery mode resonator, WGMR [1]) using a self-injection locking technique [2]. This technique results in the complete suppression of the mode hops in the laser during the lifetime of the laser chip. The microcavity will be used not only to stabilize the frequency of the laser, but also to measure and stabilize the power of the laser to the level of 10 ppm per 1s and longer. The overall performance of the laser and SWaP (size, weight and power) of the device will correspond to the stringent requirements of the Call. The lasers will be tested by UCLA team.
