Coherent launches new UV fiber laser Daytona™

Coherent launched a new type of ultraviolet fiber laser Daytonau0026trade; 355-20, which not only provides the precision processing capabilities of short-pulse picosecond lasers, but also has the high throughput of diode-pumped Q-switched solid-state lasers. The sub-nanosecond pulses emitted by Daytona 355-20 can provide more than 20W of power with a repetition frequency of more than 1MHz (wavelength 355 nm).　　 In addition, Daytona can achieve TEM00 (M2 <1.3) output beam, which makes it an ideal choice for precision micromachining. Moreover, Daytona is a highly flexible platform that can be adjusted in a wide range of work to meet the actual needs of specific applications. For example, the pulse width can be adjusted from less than 1ns to 20ns, and the repetition frequency can be adjusted from single pulse transmission to more than 2MHz.　　The key to micromachining without thermal damage (heat-affected zone HAZ) around it is to drive cold ablation with a very short wavelength, and use short pulse width to limit the heat conduction during the ablation process. Traditional Q-switched UV lasers provide pulse widths of tens of nanoseconds, which can create heat-affected zones that are unacceptable for many applications. Before the launch of Daytona, people's choice was to use lasers with pulse widths up to tens of picoseconds, but these light sources did not provide high enough output power in the ultraviolet band to meet high-throughput industrial needs. Therefore, Daytona is a precise, high-power laser source for these applications.　Daytona is suitable for applications including wafer cutting, scribing, drilling (especially low-k materials), glass scribing for touch screens and liquid crystal displays, touch screen engraving, and thin film scribing in the field of solar manufacturing.
