  1. Rochester Institute of Technology-Proposal to join the LSC- Shally SarafRochester Institute of Technology Quantum Electronics Group (RITQEG) LIGO-G060437-00-Z August 15, 2006

  2. Who is RITQEG? • Shally Saraf- Part of LSC since 1999 - 1999-2005: Graduate student in Bob Byer’s high power laser lab at Stanford - 2005-present: Asst. Prof. Electrical Engineering, RIT • Two MS students from electrical engineering • Potentially a few undergraduate students from EE and Physics

  3. Where is Rochester, NY?

  4. Rochester Institute of Technology • Founded in 1829, moved to Henrietta campus 1968 • Current Enrollment 15,200 students - 85% undergraduate - 6600 resident on campus • 50% from New York State • Ph.D. program in Microsystems engineering • 2,700 faculty and staff • 360 career-oriented and professional programs • Extensive cooperative education program - 1,300 companies - 3,000 students

  5. Rochester Institute of Technology… • Eight Colleges - The College of Applied Science and Technology - The College of Business - The B. Thomas Golisano College of Computing and Information Sciences - The Kate Gleason College of Engineering - The College of Imaging Arts and Sciences - The College of Liberal Arts - The College of Science - The National Technical Institute for the Deaf

  10. RIT “Tigers”

  11. Research interests of RITQEG • High power solid-state lasers • Quantum noise measurements • Squeezed light generation • Terahertz generation and imaging

  12. Past research for LIGO • Developed 100-W class Nd:YAG MOPA for Advanced LIGO • Performed quantum noise measurements in free-space saturated amplifiers • Developed Resonant Cavity Polarizers

  13. 100-W-class zigzag slab amplifier • 90% in TEM00 mode at • 104 W output power!

  14. Amplifier quantum noise measurements • Extraction efficiency increases and quantum noise • decreases as the amplifier is saturated!

  15. Proposed work • Build a compact OPO-based squeezer at RIT - start off with PPLN/PPKTP - investigate other low-loss, high non-linear coefficient materials (GaAs?) - achieve >10 dB squeezing with “squeezer-in-a-box” • Investigate frequency-dependent squeeze angle generation - cavities and other techniques (EIT?) • Develop collaborations within LIGO - Nergis’s group at MIT

  16. Squeezing at the 40 m • >2 dB squeezing achieved in PPKTP! • OPO and homodyne detector to be optimized • Several PPKTP crystals to be tested • Quantum noise locking of OPO to be implemented

  17. Proposed work for the period August’ 06- August’ 07 • Design test bed for qualifying nonlinear crystals for squeezer. Start off with PPKTP (?) to develop a baseline similar to the MIT design. • Design and build PPLN based SHG for pumping OPO. • Design and build quantum noise locking (QNL) servos for locking OPO and squeeze angle.
