Syllabus
  • 1. Principles of laser technology: Einstein's laws on the issue and the absorption of radiation, the concept of coherence radiation, inverse population, metastable state of atoms and molecules, active environment.
  • 2. Amplifier and generator of radiation. Optical feedback, resonators, modes, quality Q, the concept of Q-modulation. Modulation of active and passive, synchronization modes, femtosecond oscillators.
  • 3 Active environment lasers: Gas lasers (He-Ne,), energy diagrams; molecular CO2, N2, HCN lasers, lasers in solid (ruby and Nd-YAG), optical pumping, pulsed and continuous operation; ion lasers (Ar); Excimer laser (KrF); semiconductor lasers (GaAs, CdHgSeTe); chemical lasers (HF).
  • 4. Continuously tunable lasers dye (Rhodamine), solid phase(Sapphire: Ti), frequency and spectral properties, construction unimodal tunable lasers. Pulsed lasers, consistency and frequency spectrum of short pulses of radiation.
  • 5. Performances of lasers: continuous, noise and stability; pulse power, the length of pulses, stability.
  • 6. Laser radiation and optical properties of materials, electromagnetic pass. radiation material environment, nonlinear optics, the absorption of radiation in surface layers of solid materials.
  • 7. Analytical applications with the use of high concentrations of energy in the jet: Laser ablation for the surface and analysis of local materials in combination with other spectral methodologies (AAS, ICP, OES), laser spark in the emission spectroscopy, MALDI.
  • 8. Laser spectroscopy unsaturated states: atomic fluorescence photoionization (one and two photons) and its analytical applications (LEI), Raman spectroscopy, absorption spectrometry UV-VIS-IR with high-resolution, optoacoustic spectroscopy, absorption spectrometry low absorbances.
  • 9. Laser spectroscopy saturated conditions (saturation spectroscopy) non-doppler absorption spectrometry one and two photons, frequency standards, high absorption spectrometry, heterodyne spectroscopy.
  • 10. Detection of individual atoms and molecules, the spatial orientation of molecules in the solid, spatial structural analysis of the nanotechnology and biology.
  • 11. Analysis of distant objects using LIDAR: analysis of gaseous emissions, smog, combat gases. Analysis of samples of dangerous at a distance: spectral analysis of radioactive waste samples at high temperatures (furnaces, reactors), unavailable (poles, drilling).
  • 12. Remote sensing and Earth's atmosphere (non-linear heterodyne spectroscopy analysis,gravitational field).
