Treatment Guidelines for the PicoWay® Laser System in Skin

Dealing with the laser fluence is important in light of the high pinnacle forces, and strategies, for example, working at higher reiteration rates, or spatial beamsplitting, are generally utilized. In any case, the speed of scanners and movement stages places restrains in usable laser reiteration rates, and spatial beamsplitting requires extra framework intricacy and cost.

With half breed fiber lasers, high-beat 伦敦皮秒— joined with heartbeat fitting, or worldly parting of heartbeats as overflows with changing heartbeat dispersing and redid beat envelopes (Figure 1a) — can be acknowledged so the episode vitality can be applied predominantly for material evacuation as opposed to overabundance warming.

In this manner, beat fitting gives an extra level of opportunity for process enhancement and can bring about enormous gains in throughput and quality without the requirement for extra expensive equipment3,4. With streamlined heartbeat fitting parameters, a 10× upgrade in removal rate over that for a solitary heartbeat can be accomplished.

Heartbeat timing control is another key ability for improving machining throughput while holding the cold-machining nature of picosecond lasers.

Filtering galvanometers, or “galvos,” are ordinarily utilized for micromachining due to their capacity to rapidly quicken the bar to high speeds, yet they are restricted in the preparing field of view, particularly for little center spots. Consolidating galvos with rapid stages can bring about quick preparing over enormous zones.

To deliver top notch machining results, be that as it may, it is important to fire the laser at a steady spatial, not fleeting, detachment over the whole movement direction. With some crossover fiber lasers, heartbeats can be activated on request and synchronized with the movement profile — called position synchronized yield (PSO) — with insignificant planning jitter.

This has been shown utilizing a picosecond cross breed fiber laser to process SnO2-covered glass with a variable speed movement direction. Without PSO, removal spot cover increments as the movement eases back, bringing about over the top consume, while with PSO, the laser-terminated spots are equally separated around the whole direction.
