“…In practice, one could potentially add multiple dispersion bounces per AMC pass with lower value per bounce, as this is typically beneficial in high average power lasers. In fact, the higher the dispersion value per bounce, the stronger the thermal effects at high average power [37]. Additionally, GDD bandwidth typically scales inversely proportionally with the GDD value, therefore small values are preferred to support larger bandwidths.…”

Since their first demonstration, modelocked thin-disk lasers have consistently surpassed other modelocked oscillator technologies in terms of achievable pulse energy and average power by several orders of magnitude. Surprisingly, state-of-theart results using this technology have so far only been achieved in modelocking regimes where soliton pulse shaping is dominant (i.e., soliton modelocking with semiconductor saturable absorber mirrors or Kerr lens modelocking), in which only small nonlinear phase shifts are tolerable, ultimately limiting pulse energy scaling. Inspired by the staggering success of novel modelocking regimes applied to overcome these limitations in modelocked fiber lasers, namely the similariton (self-similarly evolving pulses) and dissipative soliton regimes, here, we explore these nonlinearity-resistant regimes for the next generation of high-energy modelocked thindisk lasers, whereby millijoule pulse energies appear to be realistic targets. In this goal, we propose two possible implementations. The first is based on a passive multipass cell and designed to support dissipative solitons in an all-normal dispersion cavity. The second incorporates an active multipass cell and is designed to support similaritons. Our numerical investigations indicate that this is a very promising path to increase the pulse energy achievable directly from modelocked oscillators toward the millijoule level while additionally simplifying their implementation by eliminating the need for operation in cumbersome vacuum chambers.

“…Since 1994, a lot of scientists have been attracted into this field. For the past 2 decades, DMs exploited as intracavity and extracavity dispersion compensation components have been widely used in all kinds of ultrafast laser systems, including Ti:sapphire oscillators [2][3][4][5], Yb:YAG disk oscillators [6][7][8], Erbium-doped fiber chirped pulse amplification systems [9], etc. [10,11].…”

“…Broadband dispersive mirrors (BBDMs) [15][16][17][18][19][20] and high-dispersive mirrors (HDMs) [2][3][4][5][6][7][8][9]13] are the two mostly used DMs. Design and manufacture of both kinds of DMs are the challenge.…”

“…However, as more complicated DMs were required to meet the dispersion control in laser systems, electron beam evaporation technique was no longer suitable for producing DMs. Magnetron sputtering (MS) [6][7][8][15][16][17][18][19][20] and ion beam sputtering (IBS) [9,21], which have improved layer thickness accuracy and process stability, became the most widespread coating processes for manufacturing DMs. Both processes deposit layers with excellent uniformity of physical thicknesses and high stability to environmental conditions compared to layers produced by electron beam evaporation.…”

Comparison of magnetron sputtering and ion beam sputtering on dispersive mirrors

et al. 2020

We have compared two kinds of dispersive mirrors (DMs) produced by magnetron sputtering and ion beam sputtering. One of them is a broadband DM which is known as double-angle DM, providing a group delay dispersion (GDD) of −40fs 2 in the range of 550-1050 nm. The other one is a robust highly dispersive mirror, which provides a GDD of about −275fs 2 at 800 nm and covers the wavelength range from 690 to 890 nm. For the first time, a comparison between magnetron-sputteringproduced and ion-beam-sputtering-produced dispersive mirrors is performed.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…With the recent improvements of the deposition and optical monitoring techniques [1,2], it is now possible to fabricate more complex multilayer structures having up to several hundreds of layers. Most of the focus on the recent developments has been placed on the precise control of the intensity transmitted or reflected by these elements, but very little efforts has been placed in the control of the reflected phase except for the control of group delay dispersion, especially for short pulse laser applications [3] or for a few specific applications including bandpass filters or mirrors [4][5][6][7]. In addition, there is higher demand for larger optical elements, which required large efforts in order to improve the uniformity of optical coatings [8].…”
