We are pleased to offer laser sources manufactured by Redfern Integrated Optics (RIO). These high-performance single-frequency external cavity lasers (ECLs) are based on RIO’s PLANEX™ proprietary planar technology. PLANEX™ lasers consist of an amplification chip and a planar waveguide structure (PLC) with an integrated Bragg grating. The combination of these elements results in a laser with a large laser cavity that has significant advantages:
- optical output power of up to 20 mW
- very low relative intensity noise (RIN)
- ultra-low phase noise and very small line width
- very low wavelength sensitivity regarding bias current and temperature
- 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:
- acoustic and seismic sensing
- LIDAR and remote sensing systems
- distributed fibre-optic temperature or strain sensing systems
- high-resolution spectroscopy
- wavelength locking and optical phase locked loops
- microwave photonic links
- coherent communications
The pin assignment and form factor conform to the industrial standard and make 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.
