Spectra Physics 7900P-L131 diode laser

Product Description

Spectra Physics 7900P-L131 Fiber-Coupled Diode Laser Module

This is a precision, telecom-grade diode laser module designed for stability and reliability in demanding optical applications. Operating at the standard 1310 nm O-band wavelength, it features single-mode fiber output with integrated thermoelectric cooler (TEC) and control electronics, making it ideal for component testing, fiber optic research, and system integration.

Key Specifications:

• Model: 7900P-L131

• Wavelength: 1310 nm (O-band, standard single-mode fiber window)

• Output Power: Typically 10-50 mW (dependent on drive current)

• Spectral Width: Narrow, single longitudinal mode

• Fiber Output: Single-mode fiber (connector typically FC/APC or FC/PC)

• Control: Integrated driver with TEC for precise wavelength and power stability

• Monitoring: Built-in back-facet photodiode for power feedback

Applications:

• Telecommunications Testing: Characterizing fibers, isolators, WDMs, and other passive components

• Fiber Optic Sensor Systems: Source for interferometric, OTDR, or distributed acoustic sensing

• Research & Development: Pump source for nonlinear optics or general laboratory infrared illumination

• OEM Instrumentation: Integration into optical measurement or analysis equipment
