New radiation sources for medical, environmental and special tasks are being developed in the laboratory.

The following tasks are being solved:

The development and exploration of new media based on nonlinear chalcogenide crystals to convert the Nd: YAG radiation into the mid-infrared range;
The study of wide-aperture periodically polarized structures of ferrielectric crystals, and the creation of tunable sources of infrared (IR) radiation in the 2-4.5 mkm high power range for special uses. Moreover the development of multi-wavelength optical parametric light oscillators with a switchable set of frequencies;
The development and research of cascading frequency converters pumped by the Nd: YAG laser in the range of 1.064 mm and continuous adjustment in the range of 7-14 microns for gas detection systems;
The study of parametric generators with the phase self-synchronization (PG-PSS) for fundamental metrology. The study of PG-PSS nonlinear dynamics as the system with cascade nonlinearity;
The study of new nonlinear media to create a converter frequency from the immediate IR and IR ranges into the THz range.
