Summary

[edit]
Description
Русский: На фото - зеркало резонатора волоконного лазера Er ZBLAN, установленное на подвижной платформе. Зелёное излучение, выходящее из волокна, появляется вследствие апконверсии инфракрасного излучения на длине волны 2800 нм, происходящей внутри волокна. Подвижная платформа позволяет смещать зеркало с микронной точностью, что крайне важно для аккуратной юстировки резонатора лазера. В щели между двумя металлическими плитами, которые отводят тепло от активной среды, можно увидеть часть волокна. Суть работы данного лазера заключается в генерации коротковолнового излучения (зелёный свет - примерно 550 нм) при условии, что накачка происходит с помощью длинноволнового излучения (ИК - 2800 нм, не воспринимается человеческим глазом).
English: There is resonator mirror of Er ZBLAN fiber laser, mounted on moving platform. Green radiation coming from the fiber emerges due to a so-called upconversion process of IR radiation with wavelength 2.8 micrometers, that occurs inside of the fiber. Moving platform allows to shift mirror with precision in 1 micron, that is important for accurate setting of a laser resonator. In slit between two metal plates, that is used to remove heat, one can see part of the fiber. The idea of this laser can be described in such a way: radiation with short wavelength (green light - approximately 550 nm) is generated, provided that pumping occurs by means of a long-wave radiation (IR - 2800 nm, it can't be seen by human eye).
