The Newport LQC980-220E is a continuous wave laser diode module delivering 190 mW of stable output at 980 nm. Built around a Fabry-Perot laser diode with integrated collimating optics, this compact module (Ø38.1 × 157.5 mm) provides an elliptical beam with 1 nm linewidth and <0.5% noise for applications demanding precision and reliability. Power stability exceeds 99% over 8 hours, while integrated temperature control maintains consistent performance across the 0 to 40°C operating range.
