The laser source employed in this case was a Ti:sapphire laser producing 100 fs pulses at 815 nm with a 76 MHz repetition rate and a maximum average power of 600 mW.. The open- and closed-aperture z-scan techniques were used in order to resolve the absorptive and refractive contributions to the nonlinearity, and were implemented using a lens with a 200 mm focal length to produce the focused ..
Connect the solar cell to the watt-meter and station it 3 feet away from the laser.. Turn the laser on so that it hits the solar cell and its power is recorded by the watt-meter.. Write down the ..
