Better green beam

I tried to change the cavity temperature to see if the beam gets better. And then at some point I got the green beam shows in the picture, it looks good and much more bright then before. And I also tried to put some filters to see if there is any detail I can not find with this brightness, but even when it's very week it still looks good.

Before when we tried to get the relationship between the temperature(resistance) and the green beam power we did not install the miniscope ,so that's maybe the reason why now we need to change the temperature a little bit to get better phase matching.

I will take some data points to get the exact new best temperature.
