How a Laser Works

Bill shows how the iii cardinal characteristics of Light Amplification by Stimulated Emission of Radiation lite – unmarried wavelength, narrow beam, as well as high intensity – are made. He explains the functioning of a reddish Light Amplification by Stimulated Emission of Radiation – the commencement Light Amplification by Stimulated Emission of Radiation e’er made – showing how electronic transitions utilization stimulated emission to hand coherent light, as well as thence how the ends of the reddish cavity utilization a narrow wavelength highly collimated beam.
