ultrafast_fluence(power_mW = 1, 
                  freq_khz = 1.05, 
                  spot_diameter_microns = 100, 
                  beam_angle_deg = 60)

Arguments

power_mW

Average power in mW

freq_khz

Repetition rate of the laser system

spot_diameter_microns

Spot diameter at normal incidence in microns

beam_angle_deg

Incident angle of beam on surface in degrees. Used to calulate ellipsity of beam spot

Value

Returns Fluence in 3 common units of measurement. Also provides a warning in relation to graphene damage thresholds [1].
