ultrafast_fluence: Calculation of Incident Fluence from a Pulsed Laser System

In tjconstant/ultrafastMonkey: Misc Tools for work in Exeter University's Ultrafast Laser Lab

Description

Calculation of the incident power per unit area (fluence) from a pulsed laser system given various parameters

Usage

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].
