TLDR
In this paper, the spectral distribution curve of temperature radiation was shown to be similar to the velocity distribution of the electromagnetic spectrum of a single photon, and the formal similarity of spectral distribution curves to Maxwell's velocity distribution curve was revealed.
Abstract
The formal similarity of the spectral distribution curve of temperature radiation to Maxwell’s velocity distribution curve is too striking to have remained hidden very long.

Laser and Microwave Generations in Nitrogen

TL;DR: In this article, the results obtained in the three sets of experiments were described and an attempt was made to relate one of these concepts to the lightning phenomena, where the ultraviolet radiation coming from the current carrying the spark channel pumps the N2 molecules to the upper-excited $C^{3}pi _{u}$ level to yield the nitrogen laser pulses at 337.1 nm of long (>220 ns) duration.

Background and General Applications

TL;DR: The basic laser consists of two mirrors which are placed parallel to each other to form an optical oscillator, that is a chamber in which light travelling down the optic axis between the mirrors would oscillate back and forth between the two mirrors for ever, if not prevented by some mechanism such as absorption.

Complex Systems and Their Statistical Description

TL;DR: Analytical description of the dynamics of multilevel quantum systems, including the results which can be obtained with the help of the statistical approach, is the main subject of this book.

Planck, Photon Statistics, and Bose-Einstein Condensation

TL;DR: In this paper, a theory of laser action was developed to account for photon statistics, i.e. fluctuations near threshold, and this was accomplished in 1965, after Bose-Einstein condensation was successfully achieved.

Basics, Laser Physics and Safety for the Clinician’s Requirements

A. B. Imhoff
TL;DR: The concept of using laser energy for medical applications dates from the early 1960s, when Theodore Maiman [27] built the first laser and found that a ruby crystal, when stimulated by a flash lamp, emitted red laser light at a specific wavelength of 0.69 µm as discussed by the authors.
