The O2 Pre-Stabilized laser system was the laser bench used for the first run of observation of Advanced VIRGO. It has been replaced by the O3 Laser bench in december 2017.


Description:

The 60 W laser bench was based on the laser bench used for VIRGO+ phase of VIRGO. It was reinstalled from automun 2013 for the building, commissiong and first run of Advanced VIRGO. The bench comprised a 20 W Nd3+:YAG laser injection locked onto a non planar ring Nd3+:YVO4 Laser and amplified by a 60 W 4 Nd3+:YVO4 cristals amplifier. The laser beam was filtered by a triangular Fabry-Perot cavity before being delivered to the injection bench of Advanced VIRGO
