Femtosecond lasers are at the forefront of laser technology, offering unprecedented precision and control in various applications. These lasers emit extremely short pulses of light, typically in the range of femtoseconds (one quadrillionth of a second), making them suitable for a wide array of uses, from medical treatments to advanced manufacturing processes. This article explores the technology behind femtosecond lasers, their applications, and the advantages they bring to different fields.
What is a Femtosecond Laser?
A femtosecond laser generates light pulses that last for just a few femtoseconds. This rapid pulse duration allows for the manipulation of materials at incredibly precise levels, enabling scientists and engineers to achieve results that are often unattainable with traditional lasers. The short pulse duration means that the laser can interact with materials without causing significant thermal damage, making it ideal for sensitive applications.
