"The grant project aims the upgrade (mode structure, divergence, time profile, pre-pulse suppression) of the third harmonic frequency of the hybrid iodine laser system SOFIA (Dept. of Nonlinear Physics, Inst. of Physics, AS CR). The hybrid laser chain SOFIA consists of the solid-state\u00A0 oscillator MOPO-HF followed by the iodine photodissociation amplifiers. The third harmonics pumps nonlinear crystals at the process of parametric amplification of a chirped signal pulse from the Ti:sapphire laser. The improvement of the parameters of the\u00A0third harmonic frequency\u00A0is essential for efficient conversion of the pump energy to the signal beam. It will be attained by inserting a new iodine pre-amplifier, modification of the last amplifier for double passing,reconstruction of the image relaying system and optical spatial filters and others. The final goal of the laboratory SOFIA is the mastering of the modern challenging OPCPA technique (Optical Parametric Chirped Pulse Amplification) for the generation of"@en .
