What Does FROG Stand For?

FROG stands for Frequency Resolved Optical Grating

FROG, or Frequency Resolved Optical Grating, is an advanced technique used in ultrafast laser physics to measure and characterize the temporal properties of ultrashort laser pulses. By analyzing the spectral components of a pulse as it interacts with a grating, FROG provides detailed information about the pulse's shape, duration, and frequency content. This method is valuable in various applications, including telecommunications, medical imaging, and fundamental research in optics and photonics.
