Our highly popular TLB-6300 Velocity lasers deliver continuous tuning over wide wavelength ranges with excellent resolution, narrow linewidths and low noise (40-dB side-mode-suppression ratio). As with all of our lasers, these lasers scan mode hop-free over the entire speciﬁed tuning range and have easy-to-use interfaces including remote GPIB (IEEE-488) and RS-232 controls. Our ﬁne-frequency piezo control allows you to set the laser’s wavelength with a resolution of 0.2 pm. And unlike lasers driven by stepper motors, ours are truly continuous and monotonic. With a choice of wavelengths from 630 nm to 1.7 µm, these lasers are ideal for spectroscopy, metrology, sensing, telecommunications, and research applications.

The Velocity lasers are available with an integrated optical isolator for free-space output. A pre-aligned optical isolator option can protect your laser from potentially damaging feedback levels with 35 dB of isolation. This isolator will also protect your experimental results as non-damaging levels of feedback can cause anomalous behavior in any laser cavity. Mechanically coupled, the isolator comes pre-aligned and ready for use. Save time and effort. These systems are also available with a fiber-coupled output.

Custom wavelengths and power requirements are available.
