Laser Components offers lasers from Redfern Integrated Optics

UK distributor Laser Components is pleased to offer laser sources manufactured by Redfern Integrated Optics.  These high-performance single-frequency external cavity lasers (ECLs) are based on Redfern’s proprietary technology, PLANEX, which consist of an amplification chip and a planar waveguide structure (PLC) with an integrated Bragg grating.

The combination of these elements results in a large laser cavity that has significant advantages, including very low relative intensity noise (RIN), ultra-low phase noise and very small linewidth, and very low wavelength sensitivity to bias current and temperature. These devices offer optical output power of up to 20mW.

The low-noise, powerful, ultra-narrow band PLANEX lasers are particularly well suited for applications that place high demands on absolute precision, lifetime – even under harsh environmental conditions in the field during application – or a high attainable resolution.

They are ideal light sources for applications including distributed fibre-optic temperature or strain sensing systems, high-resolution spectroscopy, wavelength locking and optical phase locked loops, microwave photonic links and coherent communications, the company says.

The pin assignment and form factor conform to industrial standards, making simple application in existing systems possible as a drop-in exchange or upgrade to improve performance. 

The lasers are also available as laser source modules with a serial interface, as a bench-top laser source, or in other configurations.
