The significance of researching and developing thermal stabilization systems for end-pumped amplifiers in high-power lasers is evident in modern optical and laser technology. There are several key factors driving this importance. Firstly, high-power laser systems have pivotal applications across diverse fields, including science, medicine, industry, and defense. Secondly, high-power laser systems generate substantial heat, resulting in thermal effects that impact their optical stability and efficiency. Thirdly, the implementation of optical thermal stabilization systems enhances the performance and durability of high-power lasers. In summary, the research and development of optical thermal stabilization systems for end-pumped amplifiers are crucial endeavors in ensuring the stability, efficiency, and reliability of high-power laser systems.
In complex optical systems conversion of their characteristics, such, as: a magnification, a focal distance, a field of vision etc., without entering of any changes into the circuitry of the instrument, is carried out by different application of nozzles. In view of the fact that they are, a removable part of an optical system, therefore, shan't influence provisions of input and output pupils of the instrument in general. Most often as those nozzles the calculated telescopic systems and continuous or variable increase are used separately. This operation is devoted to the analysis of the pancratique nozzles with the smooth magnification, with a possibility of their application in high-aperture systems.
The article presents the research result and the optical design of long-focus telephoto lens for photo shooting by the academician Maksutov’s scheme. It shows a review of lenses for photo shooting on the market today, and also an analysis of the correctional possibilities which is based on the scheme is presented; studied long-focus telephoto lens is compared with its closest analog, the calculation of a new telephoto lens with higher image quality is made on the basis of that comparison.
