 		Hi

A scope screen shot (Tektronix 1 Gigahertz 11402) corresponding to the picture of the complete experimental setup above.
x: 5ns/division, y: 1mV/division

Foto12400x295

The time between the two pulses is about 4 ns.
In this experiment the distance between beamspiltter and the corner cube was about 60 cm.

Regards

Physikfan
