The course aims to expand understanding of modern applications of lasers in nanophotonics for students with basic knowledge of laser physics, optics and solid state physics. The first part of the course introduces the basic principles of operation of laser light sources, including ultrashort pulse lasers and nanolasers. The second part of the course provides an overview of the use of lasers for nanophotonics problems. In particular, examples of local optical heating and nanothermometry, ultrafast modulators and optical signal converters, as well as various methods of nanofabrication using lasers are considered.
