Sg. Grubb et al., SOLID-STATE LASER PUMPING OF 1.5-MU-M OPTICAL AMPLIFIERS AND SOURCES FOR LIGHTWAVE VIDEO TRANSMISSION, Journal of lightwave technology, 11(1), 1993, pp. 27-33
An optical power amplifier and a laser source are demonstrated at 1.5
mum. A diode-pumped Nd : YAG laser is used as the pumping source for a
n Er/Yb co-doped gain medium. The power scaling advantages of this app
roach are demonstrated. Up to +21 dBm of output power is obtained from
the Er/Yb amplifier and up to +19 dBm is obtained from the laser sour
ce. The Er/Yb power amplifier, was deployed in a 42 channel AM link wi
th 40 km of fiber, and an optical loss budget of 18 dB was demonstrate
