Pulse Energy Theory
Basic Energy Relations
Pulse energy is the total electromagnetic energy contained in a single laser pulse, fundamental to understanding pulsed laser performance.
E_pulse = P_avg / f_rep
P_peak = E_pulse / τ_pulse
Duty_Cycle = τ_pulse × f_rep
Temporal Characteristics
The temporal profile of laser pulses affects energy distribution and peak power calculations.
- Gaussian pulse shape factor: 0.88
- Square pulse shape factor: 1.0
- Sech² pulse shape factor: 0.65
- FWHM to 1/e² conversion varies by shape
Energy Distribution
Understanding how energy is distributed temporally and spatially in laser pulses.
- Peak power occurs at pulse maximum
- Average power = pulse energy × repetition rate
- Energy fluence = pulse energy / beam area
- Power density = peak power / beam area
