I am going to be talking about the types of lasers in physics. There are different types of lasers, and I will talk about each type. A laser is a device that emits light through a process called “stimulated emission.” Lasers work by having lots of atoms or molecules release their energy all at once in one direction. The photons from these atoms or molecules then stimulate other atoms or molecules to also release their energy all at once, but in the opposite direction – this is how lasers get their bright beam.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. When we talk about what types of lasers there are, we’ll be talking about this process and how it happens – and what makes one type different from another. There are three basic types: gas lasers, solid-state lasers (also known as semiconductor or diode lasers), and chemical lasers. Gas Lasers were invented in the 1960s by Nobel Prize winners Charles Townes and Arthur Schawlow; they use molecules similar to hydrogen for fuel. Solid-state lasers were also invented in the 60s by Theodore Maiman; these work with materials such as neodymium which emit infrared wavelengths when electrically stimulated. Chemical Las
