2002 Vescent Photonics was founded by Dr. Mike H. Anderson. He is the lead author of „Observation of Bose-Einstein Condensation in Dilute Atomic-Vapor“ (1995).
The focus of Vescent is to develop and manufacture technologies like waveguides, electro-optics, tunable lasers, and electronics for precision laser control.
The SLICE series combines low noice analog circuitry with digital user interface including touch screen and progammable I/O-monitor.
Absorption cell for use in atomic clocks as saturated absorption high precision frequency reference. The cell is thermal stabilized and magnetically shielded. The unit is compatible to the VP-D2-DBR100 Laser and all driver and loop units of the D2-series.
The D2-125 High Speed Laser Servo is an ultra-low noise and broad band control loop. Laser can be looked an absorption lines to serve as an absolute frequency standard. Typical applications are atomic clocks, Pound-Drevel-Hall cavity locking and laser stabilization and control. The D2-125 can also be used to reduce the line width of laser sources to facilitate spectroscopy of single molecules. The included Lock Guard detects when the servo loop filter has gone out of lock and automatically tries to recapture lock.
The D2-105 Laser Controller is a precision diode laser current source based on the Libbrecht-Hall circuit. With a current noise density <100 pA/√Hz, the D2-105 has lower noise than any other commercially available laser controller. This ultra-low current noise is ideally suited for use with the D2-125 laser servo. Using the two devices in combination allows the realization of ultra-stable and -narrow lasers.
The D2-100 Distributed Bragg Reflector Laser is a mechanically robust laser, which is, due to no moving parts, extremely insensitive against vibrations. Furthermore, the laser can be current tuned over more than 40GHz mode-hop free. Available Center Wavelengths (nm): 760, 767, 770, 780, 785, 795, 852, 895, 920, 976, 1064, 1083.
The D2-135 Offset Phase Lock Servo (OPLS) is designed to stabilize two lasers via Difference Frequency Generation (DFG). The D2-135 works together with the D2-250 Heterodyne Module and the D2-160 Beat Note Detector. The D2-250 overlaps the master and slave lasers and launches the optical beat note into a multimode fiber where it is delivered to the D2-160, converted to an electrical beat note and supplied to the D2-135.
