Power Consumption Calculation Formulas

Total Input Power

P_input = P_laser/η + P_cooling + P_pump + P_control + P_aux

Where η is wall-plug efficiency and P_laser is output power.

Daily Energy Consumption

E_daily = P_input × DC × t_op

Where DC is duty cycle and t_op is daily operating hours.

Operating Cost

Cost = E_consumed × Rate + P_peak × Demand_charge

Including both energy charges and demand charges.

System Efficiency

η_system = P_output / P_total_input × 100%

Overall efficiency including all system components.
