“…On the other hand, such a short pulse configuration is more sensitive to the synchronization accuracy of the seed and pump pulses. A number of pump lasers were developed for OP-CPA pumping, employing amplifiers based on Nd-doped laser crystals: Nd:YAG 35−37 , Nd:YLF 38 , Nd:YVO 4 39,40 , hybrid setups that use Nd:YVO 4 and Nd:YAG amplifiers 41,42 , and even a combination of Yb and Nd amplifying media 43,44 . The diode-pumped solid state laser (DPSSL) technology, which replaced flashlamps with laser diode modules, made these pump lasers more efficient, compact and capable of operating at kHz repetition rates.…”

The generation of power-and wavelength-scalable few optical cycle pulses remains one of the major challenges in modern laser physics. Over the past decade, the development of table-top optical parametric chirped pulse amplificationbased systems was progressing at amazing speed, demonstrating excellent performance characteristics in terms of pulse duration, energy, peak power and repetition rate, which place them at the front line of modern ultrafast laser technology. At present, table-top optical parametric chirped pulse amplifiers comprise a unique class of ultrafast light sources, which currently amplify octave-spanning spectra and produce carrier-envelope phase-stable, few optical cycle pulses with multi-gigawatt to multi-terawatt peak powers and multi-watt average powers, with carrier wavelengths spanning a considerable range of the optical spectrum. This article gives an overview on the state of the art of table-top optical parametric chirped pulse amplifiers, addressing their relevant scientific and technological aspects, and provides a short outlook of practical applications in the growing field of ultrafast science.

“…The active medium design and material choice can be optimized to decrease the thermal lens, e.g., in thin-disk lasers [9,10,11,12]. Still, the higher pump powers and the increased beam size needed for energy and power scaling, make the thermal lens in the active medium the most severe limitation to be overcome [13,6,14]. For these reasons an optical layout has to be chosen that minimizes the changes of the beam propagation for variations of the thermal lens of the active medium.…”

We present a novel architecture for a multi-pass amplifier based on a succession of optical Fourier transforms and short propagations that shows a superior stability for variations of the thermal lens compared to state-of-the-art 4fbased amplifiers. We found that the proposed multi-pass amplifier is robust to variations of the active medium dioptric power. The superiority of the proposed architecture is demonstrated by analyzing the variations of the size and divergence of the output beam in form of a Taylor expansion around the design value for variations of the thermal lens in the active medium. The dependence of the output beam divergence and size is investigated also for variations of the number of passes, for aperture effects in the active medium and as a function of the size of the beam on the active medium. This architecture makes efficient use of the transverse beam filtering inherent in the active medium to deliver a beam with excellent quality (TEM00).

“…For example, Vaupel et al generated a 200 ps pulse with a narrow spectral bandwidth of 10 pm by using the spectral filtering method. 21) Okishev and Hemmer et al also used a volume Bragg grating in a regenerative amplifier for spectral selection. 22,23) Pulse stretching by frequency chirping 24) is another method for obtaining stable hundred-picosecond pulses.…”

We have demonstrated a seed source for an optical parametric chirped pulse amplification pumping source through a cryogenically cooled Yb:YAG regenerative amplifier, which can vary the pulse duration depending on the number of passes and generate a very high chirp rate. The Fourier-transform-limited pulse duration of 10 ps was extended to a few hundred picoseconds (109 to 165 ps) to prevent damage to the gain medium in the subsequent high-pulse-energy pumping source, which was seeded by the regenerative amplifier. This was achieved by inserting a transmission diffraction grating pair inside the cavity of the regenerative amplifier. The variable pulse duration could be set between 109 and 165 ps by electronically adjusting the pass number of pulses inside the cavity. The stretched pulse duration and the spectral width as functions of the pass number were characterized by considering the dispersion from the grating stretcher as well as the gain narrowing effect.
