• Designed for High Power Applications
• 1550 nm Center Wavelength
• Highly Reliable InP Ridge Waveguide
• Butterfly-Packaged Configuration

This Fabry-Perot, high-powered laser, the FPL1009SXL has a typical center wavelength of 1550 nm, which is in the eye-safe wavelength range where the cornea and lens absorb the light. Thorlabs’ FPL1009SXL is a high-power, butterfly-packaged laser that is coupled to a 1.5 m FC/APC nonpolarization-maintaining single-mode fiber. An integrated thermistor allows the FPL1009SXL to be temperature controlled, thus stabilizing the lasing wavelength and power. The FPL1009SXL is hand selected for its exceedingly desirable specifications and offers higher output power and a narrower spectral bandwidth than the FPL1009S.

The FPL1009SXL 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. The FPL1009SXL is ideal for use as source lasers for free-space optical communication or in a laser transmitter for remote sensing applications.
