basic information
**Beam Characteristics** Wavelength: 355nm (UV) Average Output: >4W Repetition Frequency: 200kHz~1000kHz Pulse Width: <15ps Beam Diameter: 3.0±0.5mm Divergence Angle: <0.3mrad Mode Quality: M²<1.2 Spatial Mode: TEM00 Polarization Direction: Linear ● High Beam Quality The Electric Light series is suitable for processing that can be handled with output in the several watt class, and by keeping the output low, it achieves a beam quality of M²<1.2, making it applicable for high-quality processing with a higher quality laser than ever before. ● Pulse Split Mode With the pulse split mode, it is possible to control low repetition frequencies, enabling processing from a single shot. ● High-Speed Processing The multi-pulse mode (burst mode) allows for processing by subdividing pulses. ● Compact Type Thanks to a revolutionary design, a significant reduction in the number of components compared to conventional oscillators has been achieved, resulting in a weight reduction of about 20kg. Additionally, the reduction in the number of components has also led to a lower price.
