Power Calculation Formulas

Average Power
P_avg = E_pulse × f_rep
P_avg = P_peak × DC

Where f_rep is repetition rate and DC is duty cycle

Peak Power
P_peak = E_pulse / τ_pulse
P_peak = P_avg / DC

Where τ_pulse is pulse duration

Duty Cycle
DC = τ_pulse × f_rep
DC = P_avg / P_peak

Fractional time laser is active

Energy Relations
E_total = E_pulse × N_pulses
E_total = P_avg × t_total
