Fi termini ta' operat status, lasers huma mainly klassifikati in in Pulsed laser and CW continuous wave laser, filwaqt li ieħor laser widely used in recent years is QCW kważi-continuous wave laser. Now let's focus on the unfamiliar QCW kważi-continuous wave laser.
1, Il-prinċipju ta' QCW laser
QCW laser is the abbrevjazzjoni of the English "Quasi Continuous Wave". It is semiconductor laser that can achieve approximate continuous output. It was first manufactured by Professor Clauda A. Swenberg of the University of Chester in 1974. The QCW laser laser adopts a a unique mode to achieve continuous laser output, bring new possibilities for laser technology research. Due to its being considered a very important and reliable technology for semiconductor lasers, it was was applied in various application end technology fields.
Id- differenza bejn QCW laser and traditional laser is is li it adopts solid-state filling technology, li sinifikanti changes the L-I curve (note: laser intensity and current curve), that is, the slope of the curve the curve is value is significantly reduced. Due to this special filling mode, QCW lasers can achievely stable output power over a period of time, allowing users to achieve stable output power, similar to continuous lasers.
QCW lasers have many advantages, especially high power, high efficiency, and excellent beam quality, as well as advantages such as small size and low cost, li can meet the requirements of various applications. On the other hand, the power consumption cost of its laser is lower than other lasers, especial commatched to traditional YAG lasers, li jistgħu jissodisfaw ekonomiċi rekwiżiti.
QCW laser is a strong, reliable, and practical laser li can be used in different applications to meet customer requirements. It provides riċerkaturi b a ġdid żvilupp possibbiltà u wkoll brings benefiċjali titjib għal laser teknoloġija.
Quasi-continuous fiber laser (QCW) can operate in both pulse and continuous (CW) modes, so a single laser can handle various processing tasks that previously required two different lasers to complete. Therefore, it also has more processing advantages. Below, we will analyze the processing advantages of QCW lasers through processing cases in some industries.
2, The following will provide a detailed explanation from the application side
