“…However, further power scaling was hindered by the anisotropic thermal properties of this material. Very recently, the first Kerr lens modelocked (KLM) [19] TDL was demonstrated using Yb:YAG generating 17 W average power with pulse duration of 200 fs [20]. Recent progress in the growth of high quality sesquioxide materials has attracted great attention [21,22].…”

We present the first passively modelocked thin disk laser (TDL) with sub-100-fs pulse duration using the broadband sesquioxide gain material Yb:LuScO 3 and an optimized SEmiconductor Saturable Absorber Mirror (SESAM). In this proof-of-principle experiment, we obtained 5.1 W of average power at a repetition rate of 77.5 MHz and a pulse duration of 96 fs. We carefully explored and optimized the different parameters on the soliton pulse formation process for the generation of short pulses. In particular, SESAMs combining fast recovery time, high modulation depth and low nonsaturable losses proved crucial to achieve this result even though they are expected to only play a minor role in soliton modelocking. To our knowledge, these are the shortest pulses ever obtained with a modelocked TDL, reaching for the first time the sub-100-fs milestone. This result opens the door to sub-100-fs oscillators with substantially higher power levels in the near future.

“…After a short time, the electron is scattered back into an unoccupied electronic state of the substrate, leaving the adsorption system excited with an energy that may be large enough to free the adsorbate. The lifetime (~ femtoseconds) of the excited electrons inside the adsorbate can be determined from ultrafast pump-probe measurements, which have only been possible recently, thanks to advancements in femtosecond lasers (25,26).…”

“…Today, Ti:sapphire crystals are the standard laser medium for achievieng both goals, due to their broad gain bandwidth that extends from about 700 nm to 1100 nm [66] and the possibility to achieve the desired mode locking by exploiting the Kerr-lens effect [67]. The laser system that has been used for most experiments in this thesis is shown schematically in Fig.…”
