실험 내용 | Adjustment and alignment of a Laser cavity via an external mirror,Auto collimation method, resonant cavity, Laser effect, |
---|---|
Study of conditions of stability of the cavity,Study of geometric properties of a laser beam(spatial profile, Gaussian beam, waist, Rayleigh length, divergence), | |
Focusing the laser beam through a lens,Study of spectra of the Helium-Neon gas,Luminescence light, monochromatic radiation, | |

실험 목적 | The Laser can be regarded as a photonic oscillator and its principle is the same as the electronic oscillator : an amplifier and a feedback loop to obtain a system of oscillations. |
The photon amplifier consists of a medium which is excited to create a population inversion. The Laser which will be studied is an Helium-Neon Laser. | |
