TL;DR: In this article, an upconversion system for field-deployable mid-infrared spectral imaging is presented, which provides a room-temperature dark noise of 0.2 photons per spatial element per second, a billion times below the dark noise level of cryogenically cooled cameras.

TL;DR: In this paper, a side-view geometry is introduced for accessing trapped particles with optical as well as other types of probe methods independent from the trapping process, which is illustrated by CARS and fluorescence spectroscopy of trapped polystyrene beads.

TL;DR: This work demonstrates a highly efficient method for converting a full image from one part of the electromagnetic spectrum into a new desired wavelength region using a nonlinear PPKTP crystal located in the high intra-cavity field of a 1342 nm solid-state Nd:YVO(4) laser.

TL;DR: The way to quantum measurements in the MIR is paved by the demonstration of a room temperature coincidence measurement with non-degenerate twin photons at about 3.1 μm by means of efficient up-converter modules.

TL;DR: All-optical assembly of microscopic puzzle pieces in a fluidic environment using programmable arrays of trapping beams to demonstrate both user-interactive and computer-automated modes of serial and parallel assembly of microscale objects with high spatial and angular positioning precision.
