“…Various amplification schemes have been developed to amplify -at a reduced repetition rate -the pulses to the and mJ region [212]. N 2 lasers [251], Nd:YAG lasers [167,[305][306][307][308][309][310], copper-vapor lasers [276,311,312], and excimer lasers [313][314][315] are used for pumping the amplifier dye cells. 12 nJ pulses of 100 fs duration could be generated at a repetition rate of 3 MHz with a cavity dumped argon ion laser as a pump source for the amplifier [316].…”

Abstract. The passive and hybrid Q-switching and mode-locking of solid-state lasers, dye lasers, semiconductor lasers and gas lasers is reviewed. The dynamics of saturable absorbers and reverse saturable absorbers is illustrated. The nanosecond pulse generation by passive and hybrid Q-switching of low-gain active media is described. The picosecond and femtosecond pulse generation by passive and hybrid mode-locking in low-gain and highgain active media is analysed. The performance data of passively and hybridly mode-locked cw femtosecond dye lasers are collected. The pulse shortening of ultra-fast pulses with saturable absorbers in intra-cavity and extra-cavity configurations is discussed. PACS: 42.55The photonic switching of lasers provides an important technique to generate short light pulses in the nanosecond to femtosecond time regime. The photons generated in the laser modify the transmission of the switching elements and cause the formation of short pulses. Saturable absorbers serve as intensity or energy dependent coupling elements in most cases. But occasionally intensity and energy-dependent refractive index changes have been applied. Nanosecond light pulses are generated in passively Q-switched lasers. The passive mode-locking of laser leads to the generation of nanosecond, picosecond or femtosecond pulse trains. The actual pulse durations depend on the spectroscopic data of the active media and of the passive elements.The nonlinear response of absorbers to light radiation is introduced in the next section [1][2][3][4][5][6][7][8][9]. The passive, and the hybrid Q-switching are discussed in . The passive, and the hybrid modelocking are described in Sect. 3. A distinction is made between the mode-locking of low-gain and high-gain active media [35 45]. The simultaneous Qswitching and mode-locking is discussed shortly in Sect. 4. A final section is devoted to the intra-cavity and extra-cavity pulse shortening with saturable absorbers [46][47][48][49][50].

Alongside the development of the more complex injection-locking technique with Ti:Sa cavities to produce these kind of laser pulses 1 , direct pulsed amplification of a continuous-wave (cw) narrowbandwidth laser source has been introduced [2][3][4][5][6][7][8][9][10] . A comprehensive overview of both laser types in light of the applications discussed here is given in 11 .…”

“…For the SLM Nd:YAG laser, the seed laser consists of a diode pump laser (1) that is focused into the Nd:YAG crystal (4) through the end mirror(2). The rest of the cavity houses a 45 degree quarter wave plate and a Faraday isolator(5), to avoid spatial hole burning, a polarizer (6), an Electro Optical Modulator (EOM, 7), a 5 mm (8) and 1 mm (9) dual etalon setup and the output mirror(10). Next, The light of the seed laser is sent through an INNOSLAB amplifier(11), pumped by a diode stack (not shown here).…”

The In-Gas-jet Laser Ionization and Spectroscopy (IGLIS) technique relies on narrow-bandwidth, high-peakpower, short-pulse-length (≈ 10 ns) and high-repetition-rate laser pulses to probe, precisely and efficiently, the hyperfine structure of medium-heavy and heavy isotopes, embedded in a supersonic jet. The power and repetition rate requirements of the laser system are met by combining ≈ 100 W, 8 ns pulse width, 10 kHz commercial Nd:YAG pump lasers with a single-mode continuous wave (cw) seeded Pulsed Dye Amplifier (PDA). The common multi-longitudinal-mode operation of these Nd:YAG pump lasers causes, however, undesirable frequency sidebands in the output spectrum of the PDA system, hindering the attainable spectral resolution, a correct interpretation and an accurate analysis of the hyperfine spectra. In this article, a new prototype Nd:YAG laser is presented, which combined with the PDA system, is capable of providing quasi transform-limited laser pulses at 10 kHz, with only limited losses in laser power. This system reduces any spectral sideband amplitude below a proven upper limit of 0.2% with one order of magnitude extra reduction expected based on simulations. A full characterization of both the Nd:YAG and PDA laser systems is done by studying the temporal and frequency behavior in detail. The study is finalized by a performance benchmark of this combined laser system in the hyperfine spectroscopy of copper isotopes, showcasing its applicability for future IGLIS studies.
