Flagship model of 15-kHz-linewidth CW Ti:Sapphire laser TIS-SF-777

Here is an example of the research in this group:

Vortex-Lattice Dynamics in Rotating Spinor Bose-Einstein Condensates

We report the observation of square vortex lattices in rotating dilute-gas spinor
Bose-Einstein condensates (BEC). By coherently transferring a fraction
of a rotating condensate in one internal atomic state to another inter-
nal state, we produce a pseudo-spin-1/2 spinor condensate. Following
a macroscopic phase separation and vortex turbulence phase, the vor-
tex lattice in each component of the BEC undergoes a transition from
an overlapped hexagonal lattice to interlaced square lattices. The sta-
bility of the square structure is proved by its response to the applied
shear perturbations. An interference technique also has been used in
the experiment to verify that the vortex lattices in both components are
interlaced, and form a skyrmion lattice. We also report recent progress
towards loading rotating BECs into optical lattice.
