pulse duration

In radar, measurement of pulse transmission time in microseconds; that is, the time the radar's transmitter is energized during each cycle. Also called pulse length and pulse width.

Thus, the use of the forming unit in the complex IK-1U allows to obtain a current pulse with the following temporal parameters: the duration of the front 10 [+ or -] 2 [micro]s at the level of 0.1-0.9 from the amplitude and pulse duration 350 [+ or -] 35 [micro]s at the level of 0.5 from the amplitude.
According to the company, the LASEROPTEK PicoLO Hand Pieces (Zoom, Fractional, Collimated, 585nm Dye & 650nm dye) delivers highly stable pulse duration, energy output and Laser Induced Optical Breakdown (LIOB) all in a compact system.
In each cycle the software applies 0.0 V during a certain delay time, then applies the voltage during the pulse duration time and finally applies 0.0 V again.
For main cut, the surface roughness increases with the increase in pulse duration time.

As a result, each studied sample contained a number of regions irradiated with the same laser pulse duration and same wavelength but different light power density.
The recent use of Pattern scan laser (PASCAL) which has a short pulse duration has shown beneficial effect on DME when used for combined presentation of PDR with DME.
Spot size was consistent between the two groups (300 [micro]m), while pulse duration was 100-150 ms for group A versus 20 ms for group B.
The laser parameters were as follows: (1) spot size of 200 [micro]m, (2) pulse duration of 20 ms, (3) type of laser spot 5 x 5 and 4 x 4 multispot arrays, (4) burn intensity of 300 mW, increased until a gray/white lesion was attained, and (5) spacing of 500 [micro]m.
In case of postpaid, CMOs are offering four to seven postpaid packages with pulse duration of 30 seconds and 60 seconds, respectively.
To understand the effect of laser on human tissue, it must be known to follow terms (Fluence, power, power density, thermal relaxation time, wavelength, spot size, pulse duration and chromophores).
Due to the subdivision of the processing and output by the sensor of the measurements into cycles comprising exposure, reading in, computation and control, the whole 400ps pulse duration is consumed at a 2.5kHz measurement rate.
