Uncooled Mini-DIL 980nm Pump Laser Module LU97**2-R

Uncooled Mini-DIL 980nm Pump Laser Module LU97**2-R Features: Up to 300mW kink-free power over full operating temperature range Operating temperature range from 0 C to +70 C (case) Polarization maintaining (PM) fibre Low power dissipation Laser chip and package design with submarine reliability The II-VI LU97**2-R uncooled Mini-DIL 980nm pump laser module is the second generation uncooled pump module providing higher power for highly reliable amplification for metro, cross-connect or other single/multi-channel amplification applications. The LU97**2-R uses a Mini-DIL package enabling low-cost and small form-factor. The G07 ridge-waveguide laser diode inside has been designed for uncooled operation at high temperature and power levels. Submarine qualification of the G07 chip ensures high reliability even at 270mW operating power, 70 C. External Fiber Bragg Grating (FBG) stabilization provides excellent wavelength and power stability over the entire temperature operating range. Wavelength stabilized by fiber Bragg grating over entire operating range Centre wavelength at 974 and 976nm Applications: Telcordia GR-468-CORE compliant RoHS compliant EDFA or EDWA requiring low-tomedium optical power with low power consumption and small formfactor package
