Take a look at what we’re working on…
Ion trap for the molecular clock.
Completed oven and electron gun assembly for Be source.
Our VUV machine.
Our valve to create an internally cold beam of H$_2$ molecules.
Alignment of the lasers used for four-wave mixing in Xe/Kr diffracted off a toroidal grating used as dispersive and focusing element. The 0th diffraction order beams overlap and a few higher orders can be observed at larger angles.
VMI image of H$_2$ photodissociation fragments.
Mechanical and electrical test assembly of the ion optics for velocity-map imaging and its mounting aids. The laser aperture can be seen at the top of the assembly and the alumina insulated wires are routed to their final position.
Our monitoring board for live tracking of lab and laser parameters, featuring an ESP32.
Calculation of ac polarizabilities, cross sections, Raman transition probabilities, … We include the effect of the continuum - which is highly relevant for weakly bound states - while handling the artificial singularities arising from the discretization.
A home-built tapered amplifier with a protection circuit for amplifying the 920 nm cooling lasers for He$_2$.
Rendering of wire trap (quarter section view).
A scanning transfer cavity locking setup to lock multiple cooling lasers by referencing them to a HeNe laser.
DBD on Amsterdam valve with visible H$_2$ discharge.
Simulation of the phase-space dynamics of metastable helium dimers captured in a red-detuned MOT, predicting a capture velocity of approximately 51 m/s.
Rendering of Be source under development, including oven, electron gun, trap and imaging optics.
