 2017-06-2311:17 [PUBDB-2017-05953] Contribution to a conference proceedings/Contribution to a book et al Towards a Fully Integrated Accelerator on a Chip: Dielectric Laser Acceleration (DLA) From the Source to Relativistic Electrons 8th International Particle Accelerator Conference, IPAC 2017, Meeting locationCopenhagen, Denmark, 14 May 2017 - 19 May 2017 2520 - 2525 (2017) [10.18429/JACoW-IPAC2017-WEYB1]   Dielectric laser acceleration of electrons has recently been demonstrated with significantly higher accelerating gradients than other structure-based linear accelerators. Towards the development of an integrated 1 MeV electron accelerator based on dielectric laser accelerator technologies, development in several relevant technologies is needed.

The resulting photoelectrons and fragment ions are captured by a double-sided velocity map imaging spectrometer and projected onto two position-sensitive detectors.

Here, we present a pump-probe experiment on the UV-induced dissociation of 2,6-difluoroiodobenzene $(C_{6}H_{3}F_{2}I)$ molecules performed at the FLASH FEL that takes advantage of recent upgrades of the FLASH timing and synchronization system to obtain high-quality data that are not limited by the FEL arrival-time jitter.

The findings are expected to be more generic than for this specific gain material.

At 1 kHz, we observe strongly bifurcating pulses, starting with certain round trip number, but the measurements identify a highly stable operation point that lies “hidden” beyond the instability region.

Nowadays, some of these blue-pumped visible lasers compete with Nd$^{3+}$-lasers in terms of efficiency and direct lasing at various colors from the cyan-blue to the deep red can be addressed in very simple and compact laser setups.
