Frequency stabilize of He-Ne laser.
Features of instrument:
Using frequency stabilized laser as the light source, the laser longitudinal mode state can be artificially controlled..
Using special high-quality hard-seal whole laser cavity, the He-Ne Frequency stabilized laser has infinite storage life and 10,000 hours of  service life.
The output power of the laser is ≥ 0.8mW, the power stability is better than 1% and the frequency stability is better than 1×10^-7.
F-P scanning interferometer: the fine constant is ≥ 100 and the free spectral is 4G.
Suitable laser beam analyzer which can be used to observe and measure the Gaussian distribution of spot intensity, spot size and divergence angle.
Complete set of equipment:
Optical experiment guide, frequency stabilized He-Ne laser, four-dimensional adjustment frame, FP scanning interferometer, laser beam analyzer, (optional), oscilloscope (self-contained) and so on
