If you need on how lasers work – from atomic physics to real-world argon-ion, fiber, and diode lasers – Silfvast’s Laser Fundamentals (2021 edition in PDF) is an outstanding choice. It is the textbook I recommend to my own graduate photonics students for both theory and lab work.
The of the 2021 edition offers:

Several key concepts are essential for understanding laser fundamentals: it releases a photon
The process of stimulated emission is the key to laser operation. When an excited atom or molecule in the gain medium decays to a lower energy level, it releases a photon, which is identical to the incident photon that stimulated the emission. This process is called stimulated emission, and it leads to an amplification of the light.
