How much do you know about lasers?

• Laser photons are coherent and in phase, leading to a stable beam diameter along its path.
• Laser intensity is constant and not subject to inverse square law.
• Three elements are required to produce a laser: an active medium, a power source, and a resonant cavity.
• The active medium can be gas, solid, or liquid.
• The power source can be electrical, optical, thermal, or chemical.
• The resonant cavity multiplies the laser intensity and can be external or internal.
• Laser beam diameter remains stable along its path due to the coherence of photons.
• Laser intensity is not subject to the inverse square law.
• The active medium determines the wavelength of the laser.
• The resonant cavity is responsible for producing the laser beam.
