Free space optical communication uses laser transmission through the air to communicate wirelessly between two locations. Lightera manufactures a broad range of erbium and erbium-ytterbium-doped fibers as well as fiber laser modules that help ensure continuous high-quality transmission through adverse weather conditions.
The Very Large Mode Area (VLMA) Erbium Doped Fiber Amplifier Module was developed to meet the growing demand for high energy and high peak power pulses across various industrial and scientific applications. Building on the advanced Lightera high power fiber laser technology, the VLMA Amplifier Module leverages Lightera’s extensive expertise in rare-earth doped fiber design and fabrication. Known for its high-power components and modules, Lightera ensures the VLMA module adheres to rigorous reliability standards required for diverse applications. This all-fiber design features a 50 μm core diameter with diffraction-limited output, available in both polarization-maintaining (PM) and non-PM versions. The large core diameter ensures penalty free amplification of high bit-rate data-communications signals to average powers of 50 W and higher. It also supports 1 ns pulse amplification up to 100 μJ with a peak power of 100 kW. Typical applications include free space communications, LIDAR, micro-machining, and femtosecond chirped pulse amplification.
The Raman Fiber Laser Module was developed to meet the growing demand for high power output across a wide wavelength range, essential for diverse industrial and scientific applications. This module advances Lightera’s high power fiber laser technology, which is renowned for its multi-kilowatt single-mode fiber lasers used in industrial machining and welding. Lightera, a leader in rare-earth doped fiber technology, combines extensive experience in fiber fabrication with a deep understanding of the reliability required for high-power components and modules. The 1480 nm Raman Fiber Laser Module is engineered as a pump-source for Er-doped fiber amplifiers (EDFAs) to enhance their performance by increasing output power and pulse energy. The single-mode 1480 nm output enables efficient in-band core pumping, shortening the active fiber length, improving nonlinear thresholds, and reducing quantum defect, thereby lowering thermal load and allowing significant power scaling. Available wavelengths range from 1150 to 1850 nm, with output power reaching up to 150 W at 1480 nm. This module is ideal for high brightness fiber laser pumping, solid-state laser applications, medical technologies, and test and measurement tasks.
