Vescent Photonics’ Dr. Juan Pino will present, “Miniature, Compact Laser System for Ultracold Atom Sensors” on Friday 14 June at 11:15 am in Room 212 A-C.

Vescent Photonics has been selected by NASA for two highly competitive phase I SBIR awards. Both research and development efforts utilize the proprietary electro-optic laser scanner technology invented by Vescent. The first award is focused on using this technology to build a micro-LADAR system as “eyes for robots”. The second award is focused on designing and building extremely small and low power optical communications modules. This will enable high bandwidth communications from cube-sat platforms to ground and airborne receivers (see figure).
Lock Guard™ auto relocking function is now available for the D2-125 Laser Servo. Lock Guard™ detects when the servo loop filter has gone out of lock and tries automatically to recapture lock. Lock Guard™ monitors the servo output and when it detects an Unlock Point (a fast change in the servo output; arrow on the red trace), it disengages the servo and holds the output at the last known valid value. Lock Guard™ waits for the Hold Time (shorter interval on blue trace) and then re-engages the lock. Lock Guard™ waits for the Settle Time (longer interval on blue trace) and if it detects that the system is still out of lock it will reset the servo output again. In the image, Lock Guard™ made three relock attempts before the challenge was removed and relock was achieved. (The beam was actually blocked and unblocked during this time.) The Lock Guard™ control parameters Unlock Point and Hold & Settle Times are all user adjustable for maximum flexibility and optimized performance. Contact Vescent Photonics for more information.
In collaboration with ColdQuanta, Vescent has a new MOT demo that we will unveil at DAMOP 2012. The demo has Rubidium (Rb) 87 magneto-optical trap (MOT) dancing to music. Check out the video below to see for yourself, or stop by our booth at DAMOP. If you’re at DAMOP, feel free to bring your own tunes and MP3 player to have the MOT dance to the beat of your own drummer! How does it work? We start with ColdQuanta’s Mini-MOT, which provides an ultra-high vacuum with large optical access. Inside the vacuum is a Rubidium dispenser which is turned on to provide a dilute vapor of Rb atoms inside the vacuum cell. Current is run through the MOT coils in an anti-Helmholtz configuration. In order to cool and trap Rb atoms, however, laser light is necessary. I’ll skip the alignment and polarization as this is a standard 6-beam MOT using 3 retro-reflections. For a Rb 87 MOT, two frequencies of light need to be used: ‘cooling’ light tuned slightly to the red of the F=2, F’=3 cycling transition; and ‘repumping’ light tuned to the F=1 transitions. We use two lasers to produce these two frequencies. The first laser is our narrow line-width CECL Laser that is peak locked to a F=1 repump transition using our Laser Servo and Spectroscopy Module. The second laser is a DBR Laser used as a slave laser. Light from the master and the slave lasers are combined on our Heterodyne Module and sent via a fiber [...]
Vescent will have a booth on the trade show floor at the 2012 CLEO conference. As usual, we will have a suite of demonstrations running, both for our long-running favorite ultra-stable cold atom laser systems and for new products. Stop by booth #1639 and talk with one of our scientists about how our technology can help your research or engineering efforts.
Dr. Sarah Bickman and Dr. Juan Pino, both Vescent staff scientists, will be presenting posters at the 2012 DAMOP meeting. Dr. Bickman will be presenting new techniques to realize very compact and low power optical shutter systems for cold-atom based experiments. Dr. Pino will be presenting a new, atomically referenced lasers system that includes a rubidium refernce cell, master laser, and frequency offset locked laser; all of this in a small butter fly package. The DAMOP meeting will be held in Anaheim, CA from June 4th through 8th.
VP of technology, Dr. Scott Davis, will be providing a technology seminar as part of an on-going series at the National Reconnaissance Office. The topic will be new techniques for realizing unprecedented optical time delays. He will present new results for realizing greater than 20 nanoseconds of tuning with optical throughputs greater than 90%.
VP of Technology Scott Davis will be presenting a paper An update on electro-evanescent beamsteerers: higher speeds (greater than 50 kHz), wider 2D fields of view (40 degrees x 10 degrees), and larger apertures (1 cm)”. Paper 8052-30 of Conference 8052 Date: Tuesday, 26 April 2011 Time: 4:50 PM – 5:10 PM More information at SPIE Defense, Security, & Sensing 2011
