How to screen a femtosecond laser pulse stream on an oscilloscope?
Reading time: 1 min 42 sec
It is quite possible to view the pulse stream of a femtosecond output on an oscilloscope screen, especially to measure the repetition rate of the laser. It is to be noted that, we cannot see the pulse shape of the laser beam as the response time (rise and fall time) of the photodiode (PD) is quite higher than the pulse width of the femtosecond laser.
Things to be noted:
