Compact Versatile Laser System for Rb BECs Navy SBIR FY2011.2 Sol No.: Navy SBIR FY2011.2 Topic No.: N112-151 Topic Title: Compact Versatile Laser System for Rb BECs Proposal No.: N112-151-0917 Firm: AOSense, Inc. 767 N Mary Ave Sunnyvale, California 94085-2909 Contact: Dong-Ik Lee Phone: (408) 735-9500 Web Site: www.aosense.com Abstract: AOSense has successfully designed and fabricated numerous laser systems for applications ranging from a rubidium Bose-Einstein condensate (BEC) apparatus to ultracold cesium and rubidium atom trapping. This SBIR topic is well-matched to our experience in designing integrated, rugged laser systems for atom-optic sensors. We propose to design and develop a compact, versatile optical system for rubidium BEC experiments that incorporates several novel concepts. The innovative technical features of the proposed laser system in this program relative to existing state-of-the-art include: (1) reduced total size of the integrated laser system, including control electronics and power supply, (2) improved frequency stability, (3) reduced operational complexity, (4) enhanced frequency agility and (5) increased immunity against mechanical vibrations and temperature fluctuations. In addition to highly detailed system and component level designs, we will perform design validation studies to ensure that the required performance specifications are met. Benefits: In ultracold atom research, the complexity and bulk of the laser system greatly limits the accessibility of research and expansion of its applications. Our proposed compact, stable, and simple-to-operate laser system holds great promise for a broad range of military and commercial applications. The proposed laser system would immediately benefit rubidium Bose-Einstein condensation (BEC) experiments, atom-optics sensors, and spectroscopic applications. Ultracold atom physics is enabling revolutionary applications in fields such as precision measurement and metrology being conducted in university, government and industry research laboratories around the world. The availability of reliable research tools such as the proposed laser system not only gives scientists and engineers access to ultracold atom research and its applications, but also amplifies the possibility of wide commercialization of these techniques. This laser system would also considerably benefit development of atom-optic inertial and gravitational sensors, which hold great potential for a wide range of military and commercial applications in navigation and geophysical exploration.
