Laser Diode by Redfern Integrated Optics

Note: Your Quotation Request will be directed to Redfern Integrated Optics.

The PLANEX™ from Redfern Integrated Optics is a Fiber-Coupled External Cavity Laser (ECL) with a center wavelength from 1530 to 1565 nm. It delivers up to 20 mW of power and has an optical isolation of 40 dB. The single frequency laser supports CW, modulated, and pulsed operations and has a wavelength tuning range of 30 pm and a modulation bandwidth from DC to 200 kHz. This laser has low phase noise and a narrow linewidth of less than 1 kHz. It has an integrated gain chip and a Planar Lightwave Circuit (PLC) that includes Bragg grating. The laser is suitable for remote sensing, distributed temperature, strain, or acoustic fiber optic monitoring, high resolution spectroscopy, LIDAR, and precision metrology applications.
