What is Semiconductor Laser Fundamentals about?

1. The document discusses the history and basic principles of semiconductor lasers. It describes how Charles Townes, Arthur Schawlow, and Theodore Maiman contributed to the development of the laser in the 1960s. 2. The basic laser process involves absorption, spontaneous emission, and stimulated emission, where stimulated emission produces coherent photons. Population inversion is needed to achieve lasing. 3. Semiconductor lasers combine the quantum electronics concepts of other lasers with a pn junction.
