Abstract:
Abstract Solid-state compact Marx generator using saturable pulse transformer (SPT) and fast recovery diodes has been proposed. The primary circuit is switched by three MOSFETs connected in parallel. The SPT functions as a step-up transformer to increase the voltage amplitude and as a closing switch for the secondary circuit. Meanwhile, all the SPTs share the same magnetic core to achieve a compact structure and ensure good synchronization. The energy storage capacitors on the secondary sides are charged through the unsaturated SPT. When the SPT saturates, the capacitors firstly transfer a lit

AbstractHigh-voltage pulse modulator has broad applications in industry. In order to pursue the qualities of compactness, solidification, and long life time, a high-voltage pulse modulator based on a helical Blumlein pulse forming line (HBPFL),a Marx generator and a self-coupling saturable pulse transformer (SPT) with fully cylindrical coaxial conductors is put forward and investigated in this paper. A new method that the fully cylindrical SPT simultaneously works as the charging pulse transformer and magnetic switch of the HBPFL is put forward and demonstrated. Traditional spark gap is substi

Abstract:
A fast-charging, discharge-switch-free Blumlein pulse forming line has been developed for high-voltage pulsed power generation. In the BL, a saturable charging inductor (CI) of amorphous metallic core is utilized and, as a result, fast-charging (charging time ≈220 ns) is obtained with a reduced prepulse. In addition, by using CI as a step-up transformer, the impedance of the output pulse can be converted to 4Z, Z, Z/4. By using the BL with a Marx generator of 300 kV and 1.1 kJ, an output of —580 kV at 24 kA and a pulse length of 60 ns are obtained, with a current rise time of less than 16 ns.

Abstract:
In this paper, an all-solid-state high voltage trigger generator is developed, which is aimed at triggering a several gigawatts three-electrode spark gap of an intense electron beam accelerator (IEBA). As one of the most important parts for triggering the IEBA precisely, it is developed based on a fractional-turn ratio saturable pulse transformer and a compact six-stage Marx generator. A pulse of rising time 141 ns and amplitude 79.6 kV is obtained on the 1000 Ω dummy load. The trigger is operated at pulsed repetition frequency over 10 Hz for testing its operational stability.

En outre, compte tenu de la demande croissante de générateurs impulsionnels fiables, en particulier pour les applications industrielles, il devient indispensable de recourir aux composants semi-conducteurs.

Microchip lasers are the most compact (~1mm3) and the simplest diode pumped solid state lasers The mirrors of the optical cavity are directly deposited on the polished faces of a thin (-1mm) laser material. They are fabricated using collective fabrication processes allowing a low cost mass production. A microchip laser has a typical size of 1×1×0.5 mm3. It is very reliable and simple to use. The microchip laser is a kind of optical transformer which transforms a poor quality laser diode beam to a diffraction limited TEM00 and single frequency laser beam Moreover, by active or passive Q-switchi

Abstract:
Mode locking with an antiresonant ring is a powerful technique for producing stable trains of ultrashort pulses. This structure1 was first applied to visible dye lasers by placing a saturable absorber within an antiresonant ring that forms the high-reflectivity end mirror of a linear laser cavity. Nearly transform-limited 65 fs pulses have been generated with enhanced pulse stability.2 By using the additive pulse mode-locking (APM) representation, we describe the antiresonant ring (ARR) as a pulse-shaping reflector, which returns a temporally narrowed pulse to the main laser cavity.

Recent progress in laser diodes with an ion-implanted fast saturable absorber resulted in generation of ultrashort optical pulses both in the gain-switching and in the passive mode-locking regimes.1-3 Normally, an implanted laser generates low intensity non-transform-limited pulses or pulse trains. Application of a fiber amplifier to increase the signal intensity and to improve the pulse quality is a promising way of obtaining soliton-like pulses.

Abstract:
We examine, experimentally and theoretically, the nonlinear dynamics of a laser which generates pulses as short as 27 fs directly from the laser (1), Fig. 1 . The laser shapes the intracavity pulses by a balanced combination of self phase modulation, group velocity dispersion, saturable absorption, and saturable gain which appears different from the shaping mechanisms in earlier lasers where the pulse shaping was due principally to saturable absorption and gain (2), or to soliton-like mechanisms in an optical fiber (3). The shaping which we discuss also offers advantages over prior modelocking

Abstract:
We have doubled the tuning range of a passively mode-locked NaCl color-center laser by introducing a low-loss intracavity frequency filter and properly preparing the NaCl gain crystal. By using a collection of bulk and multiple-quantum-well III–V saturable absorbers and II–VI quantum-well saturable absorbers, we obtained passive mode-locked operation over the wavelength range of 1.5–1.7 µm. To provide sufficient wavelength restriction without introducing excess bandwidth limiting or loss, we replaced the biréfringent plate of previous systems1 with a tunable frequency filter,2 formed by a pair

Abstract:
In recent years, many solid-state lasers have been mode-locked successfully, using the additive pulse mode-locking (APM) principle. It has been shown that, under appropriate approximations, the theory of APM is congruent with that of saturable absorber mode-locking, supplemented by self-phase modulation and group velocity dispersion. When the shortest pulses are achieved, the pulses behave like transform-limited solitons, perturbed by the gain-bandwidth limiting and the APM action. In this limit, a perturbation theory is feasible that is closely related to that of soliton perturbation theory.
