1)
What is LASER?
Light Amplification by Stimulated Emission of Radiation
Light Amplitude by Stimulated Emission of Radiation
Light Amplification by Stimulation Emission of Radiation
Light Amplification and Stimulated Emission of Radiation
2)
As distance increases, what happens to the intensity of the laser beam?
Increases
Decreases
No change
Does not depend on distance
3)
What is the minimum value of the spot size of a laser beam along the beam axis called?
Confocal parameter
Rayleigh range
Beam waist
Beam width
4)
The relationship between beam width and divergence is due to:
Interference
Refraction
Diffraction
Dispersion
5)
The constant 'eta' is the characteristic impedance of the medium in which the laser beam is propagating. What isit's value for free space?
377 ohm
277 ohm
255 ohm
355 ohm
