Photon beams from a tunable laser are used to selectively excite and promote cloud of atoms or molecules from ground state to higher excited states in resonance ionization. Resonance ionization is a process in optical physics used to excite a specific atom (or molecule) beyond its ionization potential to form an ion using a beam of photons ...
Laser radiation being delivered via a fiber for photodynamic therapy to treat cancer. A 40-watt CO 2 laser with applications in ENT, gynecology, dermatology, oral surgery, and podiatry. Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, [1] photorejuvenation, and laser surgery.
The beam of a single transverse mode (gaussian beam) laser eventually diverges at an angle that varies inversely with the beam diameter, as required by diffraction theory. Thus, the "pencil beam" directly generated by a common helium–neon laser would spread out to a size of perhaps 500 kilometers when shone on the Moon (from the distance of ...

Excimer laser was proposed in 1960 by Fritz Houtermans. [1] The excimer laser development started with the observation of a nascent spectral line narrowing at 176 nm reported in 1971 [2] by Nikolai Basov, V. A. Danilychev and Yu. M. Popov, at the Lebedev Physical Institute in Moscow, using liquid xenon dimer (Xe 2) excited by an electron beam.
Around 1980, Michael W. Berns, a professor of biology at the University of California, Irvine, founded an institute focusing on the then-new technology of lasers.After receiving a National Institutes of Health biotechnology grant, [3]: 328–331 he established a laboratory for laser microscopy, the Laser Microbeam Program (LAMP).

laser wakefield acceleration (LWFA): A laser pulse is introduced to form an electron plasma wave. laser beat-wave acceleration (LBWA): The electron plasma wave arises based on different frequency generation of two laser pulses. The "Surfatron" is an improvement on this technique.
