  In fact it is not easy to sent the laser beams to somewhere in order to test them. In our experiment there are optical spectrum analyser, optical detector, and beam profile analyser using to test the beam qualities. We can measure the laser wavelength, temporal properties, brightness and so on. These are all very important to test a new laser cavity design.
