New Focus unveils widely tunable laser diode for the 2 µm spectral region

Nov. 20, 2014
New Focus (Santa Clara, CA), which is a part of Newport, has added a 2-µm-region laser to its Velocity line of wide-tuning-range laser diodes, a line that already has tunable laser diodes with center wavelengths ranging from 638 to 1600 nm.

New Focus (Santa Clara, CA), which is a part of Newport, has added a 2-µm-region laser to its Velocity line of wide-tuning-range laser diodes, a line that already has tunable laser diodes with center wavelengths ranging from 638 to 1600 nm.

The TLB-6736 Velocity has a mode-hope-free tuning range of 1975 to 2075 nm, a typical power output of 2 mW at 2030 nm, and a maximum tuning speed of 20 nm/s.

Lasers emitting at around 2 µm are not only eye-safe, but also have a variety of applications that include mid-IR frequency combs, molecular spectroscopy for ground measurements, atmospheric monitoring, and seeding thulium (Tm)-doped fiber amplifiers.

“We have received many requests for a 2 µm laser over the past several years," says Diana Warren, product marketing manager for New Focus tunable lasers and modulators. “It was not available anywhere else on the market. Other tunable lasers are well below 2 µm and QCL [quantum-cascade laser] wavelengths are above 3.5 µm. The decision to offer the TLB-6736 as a catalog model instead of a custom system was largely driven by customer request.”

The TLB-6736 Velocity is a tunable-external-cavity laser diode that can be fine (piezo) and coarse (DC motor) mode-hop-free tuned. It operates in single mode and provides a 200 kHz linewidth (measured over 50 ms).
