The result of studying the course "Experimental Non-Linear Optics" is students' acquisition of knowledge about: characteristics of non-linear polarization of medium; classification of non-linear phenomena (by rank of non-linear susceptibility tensor), characteristics of these tensors; principles of light amplification and generation; physical mechanisms of inversion and light amplification in active media; principles of laser radiation formation in the resonator; ability to solve equations for related amplitudes of electromagnetic waves under certain conditions (in particular, in second harmonic generation and parametric frequency conversion) and apply the acquired knowledge working with lasers and studying scientific literature; knowledge of the physical characteristics and mathematical descriptions of nonlinear phenomena listed above (in particular, energy relations and conditions of phase synchronism in second harmonic generation and for parametric frequency conversion).

Lectures

Assessment of knowledge is carried out according to the module-rating system, which consists of 2 parts. The knowledge assessment system includes current, modular, and semester control of knowledge. The results of students' learning activities are evaluated on a 100-point scale. Forms of current control: the evaluation of oral answers (student can get a maximum of 20 points for oral answers) and the writing of essays (10 points). Forms of modular control: modular test (student can get a maximum of 30 points for the test). The final semester control is conducted in the form of an exam (40 points). Conditions for admission to the final exam: a student is not admitted to the exam if he scored less than 36 points during the semester.
