TOPTICA DFB pro 633 distributed-feedback laser

TOPTICA introduces the DFB pro 633, the latest in the company’s range of mode-hop-free tuneable lasers for metrology. Offering a mode-hop-free tuning range of 200 GHz and driven by the DLC pro controller, it is ready to be integrated into OEM customers’ tools.

The DFB pro range of single-frequency lasers, based on a distributed-feedback (DFB) diode, cover wavelengths from 633 and 760 nm up to 3500 nm and offers a mode-hop-free tuning range of up to 1400 GHz. They are suitable for a variety of applications, including semiconductor metrology and spectroscopy.

DFB lasers unite wide tunability and high output power. The frequency-selective element — a Bragg grating — is integrated into the active section of the semiconductor and enables continuous single-frequency operation. Due to the absence of alignment-sensitive components, DFB lasers exhibit good stability. The lasers work under adverse environmental conditions — even in the Arctic or in airborne experiments.
