Entry   Characterizing Focus Tunable Lens, posted by Fatematuj Johora at Optical room about lasers and optics Updates_of_Focus_Tunable_lenses.pdf
Yesterday Ronic and I worked on the high laser power measurements with the Vertical set-up of the Focus Tunable Lens. We went upto 38W@4 dpt at the begining
and then also changed the focal power at 38W.

Observation:
Entry   Laser FP operation, posted by Daniele Nutarelli at Optical room about lasers and optics IMG_20230922_105006_resized_20230922_111612040.jpg
This morning FP Laser was operating well locked at 30 KWatts in stable vay.

There are some fluctuations due tu pointing instabilities probably dues to temperature fluctuations in de bunker.

In the attacced picture are reported the lock parameters and signals.
Entry   Tests of pointing stability of the laser CFP, posted by Daniele Nutarelli at ThomX igloo about lasers and optics IMG_20231003_155009_resized_20231009_103610100.jpgIMG_20231003_155458_resized_20231009_103610449.jpg
Last monday with Victor we have cheked the stability of de pointing of the laser FP.

The climatisation was operating since 3 days in satble way. The laser pointing was very stable before to inejct in to the cavity (picture 1)
and also for the reflexion from the cavity (picture 2).
