NLS-Glossary

Ultra-fast lasers are typically in the pulse width range of 10 femtoseconds to 10 picoseconds.                                                                                                                                      

Picosecond fiber lasers operate in the 10 picosecond to 1 nanosecond pulse width range. These are not classified as “Ultra-fast”. Ultra-fast is generally associated with special architectures that generate pulse widths below 10 picoseconds, and most often in the femtosecond range.

Pump laser diodes that are used for fiber lasers are fiber coupled device generally based on AlGaAs III-V semiconductor technology emitting in the 800-1000 nm range most often 915 or 976 nm. 

The area which precedes the first printed bar of the start character, and follows the last printed bar of the stop character. This area should be free from any printing, and should be of the same color and reflectance as the background of bar code symbol. The clear area should be ten times the width of the narrowest element in the bar code, or 0.25 inch minimum.

A technology that connects devices using electromagnetic waves instead of physical cabling.                                                                                                                                   

Specifies the ratio between the widths of the wide and narrow elements in a barcode.
