New Focus introduces the TLB-6900 Vortex II series Tunable Lasers
The Vortex II series tunable lasers are very suitable for precision applications, where frequency stability is of primal importance.
The Star-flex motion actuator and the magnetic damping are an entirely new design and take care of a splendid frequency stability. Mechanical resonances are reduced so that results of the highest order are being achieved as well as with open-loop as with frequentie-locking.
Star-flex is a unique design with only rotational movements without translations. It is a stiff concept with minimal sensitivity for temperature influences. Hence, no positional errors occur in the nanometer range that could cause mode-hops and jitter.
The Vortex II laser functions optimally with the Vortex 6000 controller, that ensures a low noise level and precise temperature stabilisation. The Vortex 6000 controller is equipped with inputs for frequency and current modulation as well as a front panel control of the diode current and PZT voltage. This controller has an RS-232 or IEEE-488 interface.
