Welcome to Lund Laser Centre

The Lund Laser Centre (LLC) is an organisation for interdisciplinary research and collaboration in the fields of optics, spectroscopy and lasers at the Lund University. At the LLC a broad range of activities are pursued within several different research divisions and groups at the engineering, sciences and medical faculties, and at the MAX IV Laboratory. Interdisciplinary collaboration across borders, organisational as well as scientific, is a guide star for the LLC. The centre comprises today about 120 scientists, including 20 professors and about 65 PhD students.

The LLC is stimulating integrated projects between different research groups, and allow them to exploit the competitive advantage of one of the major European constellations of researchers in light/matter interactions. This has a great impact on the centre’s research and constitute a substantial added value. Directly after its establishment, the LLC was successful in its application to the EC as a "European Large Scale Facility", and after favourable evaluations and follow-up applications it has remained at this status of European excellence. The LLC is one of the founding members of the EC consortium Laserlab-Europe, presently comprising 35 leading laser research infrastructures in 18 EU countries. International research groups frequently visit the LLC within the EC supported Access Programme of Laserlab Europe.

LLC Topical Group

The LLC topical group on “advanced diagnostics” will restart on Wednesday December 14, with a lunch presentation, 12.15-13:00, by Dr. Ali Hosseinnia, Div. of Combustion Physics, who will talk about “Single-shot control of rotational coherences by fs/ns coherent anti-Stokes Raman Spectroscopy (CARS)”. The seminar will take place in room E421, Division of Combustion Physics. Baguettes will be served. Below is a brief abstract of the presentation.

Abstract

Ultrafast rotational CARS creates a quantum wavepacket of rotational coherences that evolves periodically in time. The time period of the wavepacket coincides with the rotational revival time of molecules undergoing non-adiabatic alignment with intense ultrafast laser pulses. This periodicity in CARS signal was exploited for the first time in our research group, in order to control the shape of resulting spectra by a train of delayed excitation pulses. Such a coherent control with low energy excitation can, for example, be used for species selective signal annihilation/amplification and spectroscopic applications in realistic (elevated pressures and temperatures) environments.

Prestigious prize to Anne L'Huillier

Anne L’Huillier has received the prestigious Wolf prize in physics 2022 for her pioneering efforts in ultrafast laser science and attosecond physics as detailed in the motivation. The prize is shared with Paul Corkum and Ferenc Krausz. You can read more about the prize and the recipients on the homepage of the Wolf Foundation.
