Matched Guiding and Controlled Injection in Dark-Current-Free, 10-GeV-Class, Channel-Guided Laser Plasma Accelerators

A. Picksley, Joy Stackhouse, C. Benedetti, Hai-En Tsai et autres

We measure the high intensity laser propagation throughout meter-scale, channel-guided LPAs by adjusting the length of the plasma channel on a shot-by-shot basis, showing high quality guiding of 500 TW laser pulses over 30 cm in a hydrogen plasma of density $n_0 …

Orbital-angular-momentum-enhanced phase estimation using non-Gaussian states with photon loss

Jinwei Gao, Jin‐Xuan Han, Zhonghui Yuan, Ruo-Qi Li et autres

This study investigates the use of orbital angular momentum (OAM) to enhance phase estimation in Mach-Zehnder interferometers by employing non-Gaussian states as input resources in the presence of noise. Our research demonstrates that non-Gaussian states, particularly the photon-subtraction-then-addition state, exhibit the best …

Laser-filament-induced condensation in an inverted cloud chamber

Aravindan Sridharan, T-J Wang, Alexandre Grégoire, Jian Ju et autres

We have demonstrated experimentally that firing a laser filament in a subsaturated zone of a cloud chamber of inversed temperature profile could induce water condensation. Initially, through ion chromatography performed on samples collected from a receptacle placed under the laser, the presence …

Can we reach very high intensity in air with femtosecond PW laser pulses?

O.G. Kosareva, Weiwei Liu, N. A. Panov, J. Peter A. Bernhardt et autres

In the course of femtosecond pulse filamentation in atmospheric density gases, the peak intensity is always limited by optical-field-induced ionization. This intensity clamping phenomenon is universal in all the cases we studied, namely, single and multiple filament regimes with and without external …

Spectroscopy and Lasing of Cryogenically Cooled Yb,Na:CaF2

Wenn Jing Lai, P. B. Phua, G. Andriukaitis, Audrius Pugzlys et autres

Absorption, photoluminescence spectra and CW lasing parameters of an Yb3+- and Na+-codoped CaF2laser crystal are measured in the temperature range from 5 K to 290 K. The crystal appears to be a promising host for broadband multi-mJ kHz CW-pumped regenerative amplification.
