New CO2 lasers tests

Today we tested the new CO2 lasers: we measured the maximum delivered power, the open loop noise and the beam profile at the laser output. For reference, we first measured the intensity profile of the WI laser, since we know this laser is working properly. Then, we measured the profile of the laser installed on the NI bench by Julien and Richard. Finally, we tested the new lasers: they are both working properly, maximum power is around 22W and 28W. Analisys of the beam profiles is ongoing, tomorrow we'll decide which of the new lasers will be installed on the NI TCS bench. TCS is completely OFF.
