There have been few kinds of lasers that can provide the pulse-duration
between sub-ns and several tens ps. Therefore, we call this time
bandwidth as "PULSE GAP." Microchio laser technology enables to generate
giant pulse with the pulsewidth categorized in pulse-gap region. Because
these lasers offer both of the high power and the high brightness,
microchip lasers are eminently useful for various fields from science
investigations to industorial usages.
