Abstract： |
The invention is a frequency abruption and model rival teaching test laser system belongs to laser teaching instrument technology field. Its features lies in it use outside cavity or semi outside helium-neon laser. A reflective mirror of said laser is fixed on piezoelectric ceramic of DC power drive, inserting a quartz body and a pressured glass sheet in laser resonant chamber, laser output beam enters interferometer. One can observe laser longitudinal mode split phenomenon by changing intersection angle of quartz body normal and resonant chamber axial line or giving a pressure on glass sheet. Rotates polarized sheet between output mirrors and scans interferometer. One can observe laser longitudinal tuning and competition. The device is simple and convenient. |
