Lasers are classified into 4 types based on the type of laser medium used: Solid-state laser; Gas laser; Liquid laser; Semiconductor laser; Solid-state laser Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation.The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. 1. By pumping and laser levels, there are two types viz. Looks like you’ve clipped this slide to already.
