• Designed for High Power Applications
• 1650 nm Center Wavelength
• Highly Reliable InP Ridge Waveguide
• High-Power, Butterfly-Packaged Configuration

This Fabry-Perot, high-powered laser, the FPL1059P has a typical center wavelength of 1650 nm, which is in the eye-safe wavelength range where the cornea and lens absorb the light before it can reach the sensitive retina. The FPL1059P is a high-power, butterfly-package laser that is coupled to a 1.5 m FC/APC connectorized polarizing-maintaining, single mode fiber. An integrated thermistor allows the FLP1059P to be temperature controlled, thus stabilizing the lasing wavelength and power.

The FPL1059P is manufactured by Thorlabs Quantum Electronics (TQE); this Fabry-Perot laser is based on quantum well epitaxial layer growth and a highly reliable ridge waveguide. They intrinsically offer high slope efficiency, which is the relationship between output power and drive current.
