SFEXM CW 1.5 µm Single-Frequency High Power Fiber Laser Module
OVERVIEW
Standard Wavelengths: 1550, 1556, 1560 nm
Custom Wavelengths: Any within the range 1532 – 1578 nm
Wavelength Tuning Range: 0.5 nm
Output Power: Up to 1 W (10-100% adjustable)
The Optromix SFEXM is a single-frequency high output power Erbium fiber laser with an ultra-narrow linewidth. SFEXM is made in a OEM module form factor and intended for use as a part of different systems. SFEXM requires an external power supply of +5 VDC and can be controlled using a computer via the software provided with the module. SFEXM provides a wide-range precise thermal wavelength tuning and a fast piezo tuning using an external PZT driver. This module consists of a seed laser and a power fiber amplifier allowing achieving up to 1 W output power with a 10-100% adjustment range.
