hi this is sophie from Newangie here this machine is our real Picosecond machine today our engineer will test 3 important parameter showing this machine the energy, the pulse width and the wavelength parameters here you can see the maximum energy of the 1 0 6 4 nanometer wavelength is 350 mj and here the frequency is 1 Hz click ready and put the foot pedal now the testihg is on this is our professional analysis tech devices we use this coherent and here vou can see nergy is changing but the energy is on 350mj or more than 350 mj here you can see the pulse wigth it about 500mj picosecond and this is the test for the wavelength you can see the wavelength is 1064nm And here can see the green line the green line shows that the output enery of this real picosecond machine is very stable 532nm testing press the readv and also the food paddle here this is the enery analyzer and also this is the testing for the stabilitv of the 532 nm the green line also shows the stability of the output enery here you can see the pulse width it's about a 500 picosecond and this is the 532nm wavelength
