Abstract

Pulsed fiber lasers with pulse durations in the picosecond to nanosecond regime can be achieved with Q-switched lasers or master oscillator power amplifiers (MOPAs) with pulsed seeds. These fiber lasers can be made robustly with compact monolithic designs capable of delivering pulse energies from nanojoules to millijoules and average powers from a few watts to hundreds of watts, sufficient for a wide range of applications including printing, remote sensing, LIDAR, microelectronic device fabrication, frequency conversion (for applications ranging from laser projection in the visible to EUV lithography through laser-plasma interaction), marking, engraving, welding, machining, etc. This was the first significant market for fiber lasers and still is a very important market segment for fiber lasers. We will not cover picosecond mode-locked fiber lasers in this chapter, since mode-locked fiber lasers are discussed in Chapter 11.
