Frequency source provides stable output
The Rb lamp physics package provides a well defined gas transition reference frequency that is used to discipline the crystal oscillator.
Lambda Photometrics has released the Stanford Research PRS10, a 10MHz rubidium (Rb) disciplined frequency source with ultra-low phase noise, excellent stability and a low aging rate It is suitable for any application requiring a stable, precision, low-noise frequency standard

Fibre-optic test equipment developer Calmar Optcom has introduced an ultrafast fibre laser designed for test applications of Sonet/STM components.
Argon laser replacement cuts size and power
Torsana's Starbright 488 laser is based on a passive feedback laser system: the 980nm diode emits a near-diffraction limited output which is then frequency doubled to give 488nm.
Stanford's approach uses the third overtone of a stress-compensated (SC-cut) crystal oscillator to produce an ultra-stable 10MHz output with very low phase noise (less than -130dBc/Hz at 10Hz offset).
The Rb lamp physics package provides a well defined gas transition reference frequency that is used to discipline the crystal oscillator.
The PRS10 has a very low aging rate (less than 5 x 10-11/month).
Additionally, the system can be phase-locked to an external source such as a 1pps GPS timing receiver, which eliminates the problem of long-term aging and frequency offsets.
A 10MHz microcontroller controls all aspects of operation and provides diagnostics, measurement and closed case calibration through a RS-232 interface.
The optional break-out connector board gives easy access for DC power, input/output BNC and RS-232 communication connectors.
The PRS10 is part of our range of frequency standards and oscillators, including the FS725 benchtop rubidium frequency standard, FS710 distribution amplifier, SC-10 ovenised crystal oscillator, FS-700 LORAN-C frequency standard, SR620/625 time interval and frequency counters, CG635 clock generator and DS series Function generators.
