pulse duration: The Full Width Half Maximum (FWHM) temporal duration of a single laser pulse from a single-shot laser or a pulsed laser with a specifc repetition rate under specifed operating conditions (IEC 60825-1:2014). pulse energy: Under the operation condition, the energy of a single laser pulse from the laser. pulsed fber lasers: A fber laser that releases energy in the form of a single pulse, a pulse train, or repetitive pulses. The pulse duration is less than 0.25 s. repetition rate: The number of pulses per second emitted from a pulsed fber laser. spectral width: A measure of the wavelength range of the laser. This standard uses the – 3dB spectral width. (The –3 dB spectral width is defned as the wavelength interval between two points of the spectral line at half the amplitude of the peak wavelength of the main longitudinal mode under standard operating conditions, called the FWHM spectral width.) wavelength: The central wavelength of the main spectral line of the laser output beam. 4. Categories The main performance parameter requirements and test methods of fiber lasers are different due to time domain characteristics. Therefore, fiber lasers are divided into pulse fiber lasers and continuous wave (CW) fiber lasers according to time domain characteristics. NOTE—Picosecond lasers and femtosecond lasers are called ultra-fast lasers, thus, in this guide pulsed fber lasers do not include fber lasers with pulse widths below nanoseconds.
