Newport's New Focus brand has introduced the Vortex Plus Blue TLB-6802 precision series, single-mode, finely-tuneable laser.
This is a tuneable blue laser that operates at 461nm, the wavelength for atomic clocks that are currently being built by National Labs and other research laboratories worldwide. The blue Vortex Plus replaces complex resonant second-harmonic generation, or SHG systems, making it suitable for research applications such as molecular and optical physics and other areas that require blue wavelength tuneable lasers.
The Vortex Plus laser head delivers a narrower linewidth than prior versions. The new feature combines with the same reliable stability (1 per cent over 1 hour) and true continuous-wave, mode-hop-free operation that New Focus’ legacy Vortex II product offers. For added flexibility, an industry-standard SMA port for direct-to-diode, high-speed modulation (useful for precise wavelength locking) is also included.
