9B8 - Semiconductor laser amplifier
IEEE Journal of Quantum Electronics, 1966The infrared GaAs injection amplifiers described have gains as high as 2000 and give output powers of 150 milliwatts when operating at 77°K and driven by a single mode. Output efficiencies of 68 percent differentiial and 50 percent overall can be obtained if the amplifier is driven by light of spectral width equal to the band-pass of the amplifier (30 ...

Annual Meeting Optical Society of America, 1988
Recently there has been a renewal of interest in the use of fibers doped with optically active ions, principally rare earths, as active devices in optical fiber communications and sensor systems. This increase in activity has been driven by improved methods for incorporating dopants into telecommunications-grade fiber, the availability of laser pumps ...

Some Other Lasers and Laser Amplifiers
2011We present further types of lasers: dye laser; chemical laser; X-ray laser; organic laser. And we discuss the principle of laser amplifiers. Another topic concerns optical damage.

Nonlinear Lasers and Amplifiers
2004Current optical transmission systems incorporate a mix of two multiplex techniques. Many different low-bit-rate channels are interlaced in the time domain (OTDM) to form a high-bit-rate channel. These high-bit-rate channels with data rates of 10 or 40 Gbit/s are then again multiplexed in the wavelength domain (WDM).
