 Title: CVBG stretching / Fiber Injection  

Before injecting into the amplifier, the pulse needs to be stretched using a CVBG, type attached.

the CVBG is to be used at a small angle, the beam shape and spectrum after the PBS is attached.

After measuring the beam profile, a mirror was placed to direct all the power for fiber injection

power before the fiber is 13 mW and the power injected is 6.19 mW
