RLM Series 1 TO 10 Watts Single and Dual Wavelength Raman Fiber Laser were developed specifically to meet the growing demand in the telecommunications industry for efficient, compact, high power, wavelength selectable single mode pump sources. These new pumps are ideal in advanced dense wavelength division multiplexed [DWDM] systems, which use distributed Raman amplification in transmission fibers as well as for pumping of remote erbium doped fiber amplifiers [EDFAs]. Raman Fiber Lasers offer significant advantages. It finds its use in multiplexed single mode laser diode combiners, by virtue of their reliability, low cost, high efficiency, and high power. Emission wavelengths can be selected anywhere in the range of 1200 nm to 1600 nm. Typical wavelengths of interest include 1365, 1395, 1410, 1427, 1450, 1455, 1480, 1487, and 1497 nm. Higher power levels, up to 10 watts, are also available for research and test and measurement applications.
