Precision medical devices continue to promote the development of femtosecond lasers

Traditional lasers are generally mutual photothermal interaction, will produce heat affected zone, in the application of medical precision instruments, limit the minimum size of clean parts processed without melting, may lead to unacceptable functional or visual damage, and generally have to be polished, deburring and other post-processing. The peak power of the femtosecond laser is very high, and the material can be melted and evaporated instantly before the heat is transmitted to the part, making the cutting precision higher, and the relative temperature is lower, almost no hanging slag, no subsequent polishing or polishing treatment, the femtosecond laser can achieve the perfect cutting of a variety of materials.

With the increasing demand of more and more people for vascular stents, peripheral stents, sea wave tubes, and minimally invasive tools, the femtosecond laser processing market share has been greatly promoted. In addition, more expensive materials and more adjustable materials are also one of the reasons for the continuous development of femtosecond lasers. Biodegradable stents are a good example, if processing with fiber lasers requires post-processing, it may reduce its capacity by about 50%, while cutting with femtosecond lasers does not require post-processing. Large mass production products such as electronic components and displays are already using this technology, constantly bringing additional market demand, which in turn pushes femtosecond laser manufacturers to develop and upgrade more advanced femtosecond laser systems.

Femtosecond lasers are already mature in terms of performance and economy or reliability. For example, the Monaco series belongs to a new generation of femtosecond lasers, whose maximum power has been continuously increased from less than 20 W to more than 60 W. The cost per watt of most femtosecond lasers has also come down. As a result, these lasers can not only help increase production, but also reduce the cost of individual parts. Earlier Monaco models have been used for several years in demanding 24/7 production environments, highlighting the higher reliability of the femtosecond laser, which in turn contributes to overall cost reduction, as well as the cost savings achieved by removing the mechanical post-processing step, which is lower for some precision cutting tasks.

Femtosecond laser can achieve streamlined automated component monitoring and processing, but also configured with matching operating software, simple and easy to use, can achieve a small batch of different equipment between the quick switch, the whole automatic operation. More suitable for thinner material cutting. Fiber lasers have a higher available power and therefore enable fast cutting and the cutting of thicker parts. So the specific choice of laser depends on the cutting material or its application scenario.
