15 Points Per Correct Answer - No time limit  



1. What does LASER stand for?
    Light Amplification by Stimulated Emission of Radiation
    Light Absorption by Simulated Emission of Radiation
    Latent Absorption of Specified Elliptical Radons
    Latent Amplification of Stimulated and Elliptical Radons


2. What particle plays the major role in the process of lasing?
    Electron
    Neutron
    Proton
    Krypton


3. What do you call an atom whose electrons have reached a higher energy state?
    Excited state atom
    Lasing atom
    Energized state atom
    Radiative atom


4. When an electron drops down from a higher energy state and recombines with a hole, what is produced?
    A photon
    A current
    A gamma ray
    Nothing, they cancel out.


5. Laser light has many features different to ordinary incandescent light. Which of these is NOT one of them?
    Intensely focused
    Coherent
    Diffuse
    Monochromatic


6. What requirement needs to be met before a medium can begin to 'lase'?
    Threshold voltage
    Population inversion
    Equal density of states
    100% slope efficiency


7. What is the minimum number of energy levels needed for lasing?
    4
    1
    3
    2


8. The wavelength of the laser light is a direct relationship with what feature of the medium?
    The energy gap between the excited state and ground state
    The amount of energy levels in the lasing process
    The density of excited state atoms
    It has nothing to do with the medium


9. What is NOT a form of laser?
    Dye
    Semiconductor
    Creatine
    Gas


10. In what decade was the first laser built?
    1960's
    1970's
    1950's
    1980's
