The main results

  1. It has been demonstrated that a superradiance is more coherent than a laser radiation. It has been shown that a correlation function of the 1st order, defining a measure of the spatial coherence, is close to 1 in the case of superradiance and is equal to 0.2-0.5 for the laser radiation. A supercoherent state is conditioned by the formation of a long-range order in the semiconductor medium at superradiant phase transition
  2. The ultrashort superradiance pulses in semiconductor lasers based on the quantum GaN / InGaN structures at a wavelength of 407 nm have been experimentally obtained. A minimum length was 1.4 ps at the peak power of about 3 watts
  3. It is shown that the effective relaxation time of polarization, which determines the interaction coherence of pulses and a medium, strongly depends on its optical gain. It is demonstrated that with a large optical gain the effective coherence time can exceed the transverse relaxation time by more than an order of magnitude
  4. Femtosecond superradiance pulses with duration of 300-400 fs at a wavelength of 1300 and 1580 nm in semiconductor structures on quantum wells and dots have been experimentally obtained.
  5. The integrated lighting systems for a compact holographic 3D printer at a wavelength of 472, 531, 655nm with a total diffraction efficiency of about 80% have been developed. The experimental facility for synthesized RGB holograms (up to 140 by 140 mm) recording has been created.
  6. A new type of 3D display with a continuous angle, created on the basis of the principles of adaptive micro-projectile autostereoscopic display construction has been proposed; the principle of work has been demonstrated and the information processing methods for this type of displays have been studied.
  7. Methods to construct the integrated virtual holographic display have been examined; several schemes of integrated lighting systems for this type of display have been proposed and patented.
