“…With the fiber pigtailed thin-film 30:70 PM coupler used in the other configuration, a half-wave plate is no longer necessary, as the coupler itself works as a polarizer transmitting only light in the slow axis. Self-similar spectra, characterized by a parabolic top and with steep edges [24], with a FWHM between 8 and 12 nm dependent on the pump power, could be obtained with a net cavity dispersion of 0.03 ps 2 . A typical output spectrum is shown in Fig.…”

“…In order to overcome thermo-optical effects, which limit the power scaling capability of these systems, several novel gain media designs, such as thin disk or slab, have been introduced [1,2]. However, due to the low single pass gain of these amplifier materials, very complex systems, such as regenerative amplification schemes, are required to obtain a reasonable output.…”

This chapter reviews the fundamentals and achievements of ultrashort pulse generation and amplification in ytterbium-doped fibers. Compact and ultrastable passively mode-locked fiber oscillators represent an ideal seed source for high performance femtosecond fiber amplification systems, which have been scaled towards kW-level average power and pulse energies well above the mJ-level. These laser systems will have significant impact in numerous scientific and industrial applications. Introduction and MotivationA number of important practical as well as fundamental research applications of ultrafast lasers appeared over the last decades, a trend initiated by the step from old dye-laser technology towards solid-state lasers. These high-power ultrafast solidstate lasers use small rods as the amplifier media, for instance, Titanium-doped sapphire as the most widespread one and have the potential to generate significantly higher pulse energies, higher powers and shorter pulse durations in combination

“…The satellite is in a 600-km polar orbit. Its mass is 300 kg and it consumes 330 W. A Nd:YAG slab laser [25,26] produces 75 mJ at 1.064 μm and 35 mJ at 0.532 μm at 40 Hz. The position of the instrument is obtained with a high degree of accuracy, on the order of 0.05 m, by using the global positioning system.…”

NASA is engaged in monitoring the health of planet Earth and exploring the other planets. For the former, global measurements of critical Earth parameters including ice sheet thickness, greenhouse gases, oxygen, wind velocity, and aerosols, are required. Highly specialized lasers, sometimes at new laser wavelengths, are needed to measure these variables. There are three approaches for this laser development being pursued by NASA. First, rather than seeking new lasers employing an empirical approach, a quantum mechanical model is used to predict better new lasers. Second, where lasers exist but the wavelength is not quite right, a technique referred to as compositional tuning was developed. Third, innovative laser designs are devised to produce laser sources at the requisite wavelengths.Reminiscent of a stop light, the STOP laser produces the red, orange, and green from a single laser oscillator.

“…Unfortunately, thermo-optical problems are observed at output powers of several 10 W in this type of laser, due to thermal lensing and thermally stress-induced birefringence, which leads to a reduction in beam quality. To overcome these problems, novel geometries of the gain media such as the disc [1], slab [2] and fiber [3] have been developed. The fiber laser is one of the most promising laser concepts.…”
