Pulse duration definition
Pulse duration means the time increment measured between the half-peak power points at the leading and trailing edges of a pulse.
Pulse duration. (Category 6) means the duration of a “laser” pulse measured at Full Width Half Intensity (FWHI) levels;
Pulse duration means the duration of a laser pulse; usually measured as the time interval between the half power points on the leading and trailing edges of the pulse.
Examples of Pulse duration in a sentence
Pulse duration 5-20ns FWHM Temporal profile Gaussian Temporal jitter Better than 1.0ns RMS Pulse to pulse energy stability Better than 2% RMS Divergence <0.5 micro radians Triggering Must be capable of both internal triggering operations and receiving external flash lamp and Q-switch triggers.
The event table provided by the OTDR measuring equipment shall be submitted, which shall provide the following data: - Event type - Attenuation - Return loss or reflectance (as the case may be) - Location (km) - Pulse duration used.

Based on all-fiber integrated technology, this is an inherently robust and stable system, which comes in a sealed package designed for OEM integration. The system is maintenance free and easily field serviceable, ensuring maximum up-time demanded by both industrial and scientific applications. The high repeti- tion rates available from the BlueCut combined with its high average power and superior beam quality allow for high throughput and increased efficiency for a fast return-on-invest. ■ Single Shot to 10 MHz ■ Air Cooled ■ All-Fiber Technology ■ Compact Design for OEM Integration ■ Robust and Stable ■ Maintenance Free ■ Remote Control < 1 % rms (over 12 h) 4 ■ SHG Frequency doubling to 515 nm ■ Inquire about options for OEM integration Identical and consistent laser performance 0 1 2 9996 9997 9998 9999 7 6 1 0 -8 -6 -4 -2 0 2 4 6 8 High Energy Industrial Femtosecond Laser 1030 nm, 515 nm Center Wavelength 1030 nm 515 nm** Maximum Pulse Energy >10 µJ* >3.5 µJ* Maximum Average Power >10 W* >3.5 W* Pulse Duration <400 fs <400 fs Spectral Bandwidth >5 nm >5 nm Repetition Rate single pulse to 10 MHz Beam Quality TEM00, M2 <1.25, (typ. <1.20)
Pulse duration. The minimum pulse must be used which permits the whole distance to be seen. This pulse width shall be different for different link distances. The exact value of the pulse used shall be determined by the operator of the OTDR. The following pulse duration figures can be considered indicative: > 0-40 km impulse duration = 2.5 microseconds > 40-80 km impulse duration = 5 microseconds > over 80 km impulse duration = 10 microseconds
Pulse duration. (Category 6) means the duration of a “laser” pulse, or the time between the half-power points on the leading edge and trailing edge of an individual pulse; “pulsed laser” (Category 6) means a “laser” having a “pulse duration” that is less than or equal to 0.25 seconds; “quantum cryptography” (Category 5) means a family of techniques for the establishment of shared key for “cryptography” by measuring the quantum-mechanical properties of a physical system (including those physical properties explicitly governed by quantum optics, quantum field theory or quantum electrodynamics); “radar frequency agility” (Category 6) means any technique which changes, in a pseudo-random sequence, the carrier frequency of a pulsed radar transmitter between pulses or between groups of pulses by an amount equal to or larger than the pulse bandwidth; “radar spread spectrum” (Category 6) means any modulation technique for spreading energy originating from a signal with a relatively narrow frequency band, over a much wider band of frequencies, by using random or pseudo-random coding; “radiant sensitivity” (Category 6) means Radiant sensitivity (mA/W) = 0.807 × (wavelength in nm) × Quantum Efficiency (QE); Technical NoteQE is usually expressed as a percentage; however, for the purposes of this formula, QE is expressed as a decimal number less than one, e.g. 78% is 0.78. “real-time bandwidth” (Category 3) for “signal analysers” means the widest frequency range for which the analyser can continuously transform time-domain data entirely into frequency-domain results, using a Fourier or other discrete time transformation that processes every incoming time point without gaps or windowing effects that cause a reduction of measured amplitude of more than 3 dB below the actual signal amplitude, while outputting or displaying the transformed data; “real-time processing” (Category 6) means the processing of data by a computer system providing a required level of service, as a function of available resources, within a guaranteed response time, regardless of the load of the system, when stimulated by an external event; “repeatability” (Category 7) means the closeness of agreement among repeated measurements of the same variable under the same operating conditions when changes in conditions or non-operating periods occur between measurements (Ref. IEEE Std 528-2001 (one sigma standarddeviation));
