SANTA CLARA, Calif., June 27, 2012 — New Focus, a Newport Corp. brand, has introduced the Vortex Plus Blue TLB-6802 series single-mode finely tunable lasers. The precision direct-diode blue lasers operate at 461 nm, the critical wavelength for next-generation atomic clocks that are being built by national labs and other research labs worldwide.
The blue Vortex Plus replaces complex resonant second-harmonic-generation systems, making it suitable for research applications such as molecular and optical physics.
The laser head delivers a narrower linewidth than prior versions. Stability is 1% over 1 h, and the laser operates in true continuous-wave, mode-hop-free fashion. An industry-standard SMA port for direct-to-diode high-speed modulation (useful for precise wavelength locking) is included.
The compatible TLB-6700-LN controller is available as part of the system or can be ordered separately. It features low-noise analog circuits that allow the user to precisely set critical operating parameters such as diode temperature and current.
Designed to automatically recognize the laser head and to designate the ideal temperature and maximum current limit, the controller provides intuitive, easy setup. It can be operated manually or remotely via the USB interface.
