Pulse Frequency Pulse frequency refers to the rate at which pulses of laser energy are emitted from a pulsed laser system and is synonymous with pulse repetition rate (PRR) or pulse repetition frequency (PRF). Pulse frequency represents the temporal frequency of laser pulses and is typically measured in hertz (Hz) or kilohertz (kHz), indicating the number of pulses generated per unit time interval. In laser engraving, pulse frequency influences engraving speed, energy deposition, and material removal rates, allowing operators to achieve desired engraving effects and optimize processing parameters for various materials and applications. |
