Sympathetic cooling of molecules using laser-cooled neutral atoms is a new technique being developed in the Hudson Lab at UCLA that may be able to cool clouds of molecular ions to their ground energy states. Molecular ions are trapped in an oscillating electric field inside a magnetooptical trap containing a cloud of ultracold neutral atoms. The collisions between the molecules and the ultracol...
The vibrational branching ratios of SrOH for radiative decay to the ground electronic state, $X{\phantom{\rule{0.16em}{0ex}}}^{2}{\mathrm{\ensuremath{\Sigma}}}^{+}$, from first two electronically excited states, $A{\phantom{\rule{0.16em}{0ex}}}^{2}\mathrm{\ensuremath{\Pi}}$ and $B{\phantom{\rule{0.16em}{0ex}}}^{2}{\mathrm{\ensuremath{\Sigma}}}^{+}$, are determined experimentally at $\ensuremath...
A 10-mm cavity length magnetooptically Q-switched Nd:GdVO4 laser was demonstrated using a single-crystalline ferrimagnetic rare-earth iron garnet film. To design the Q-switching system, the magnetic, optical, and magnetooptical properties of the garnet film were measured. The diode pumped solid-state laser cavity was constructed using a 190-μm-thick garnet film with 58% transmittance. The garne...
The possibility of magnetic anisotropy engineering of ultrathin Co films in the scale of several dozen nanometers is investigated by magnetooptical magnetometry. In Au/Co/Au sandwiches the spin reorientation transition from the out-of-plane to the in-plane configuration is observed, when Co layer thickness exceeds 1.9 nm. Molybdenum as the underlayer suppresses the Co thickness range for which ...
Surface magnetoelastic waves are coupled elastic and magnetic excitations that propagate along the surface of a magnetic material. Ultrafast optical techniques allow for a non-contact excitation and detection scheme while providing the ability to measure both elastic and magnetic components individually. Here we describe a simple setup suitable for excitation and time resolved measurements of h...
