We start of power output from amplifier of 1W with only the first and second stage on then we start with the third stage power increase,
Note: when changing the current on the third stage 4 diodes, better to do it step by step for each one with a step of ~ 0.5 A

- we placed at the transmission point a splitter the transmitted power before was 35 mW after placing it we had 26 mW
- 97 % transmission , 3% reflected which goes to the beam profiler
- We see degeneracy modes at the last step of 42.16 mW , so we started to test the D-shaped mirrors
- the full range of the motors is 50.8 mm
- each step = 30 nm , 30 000 steps = 1 mm
