The original femtosecond laser in the laboratory is now being used in a series of industrial micromachining applications, and is increasingly expected by the glass processing industry. Depending on the application or the data, the micro-machining equipment that blends the femtosecond laser provides manufacturers with a more profitable way to process smaller, thinner parts to satisfy the expense of electronics, medical, car shopping, and more. The needs of many shopping malls. Driving this trend is a femtosecond laser that is getting smaller, more powerful, includes a wider range of wavelengths, and offers lower quotations.
Glass femtosecond laser processing
Ultrafast pulsed lasers typically have a pulse length of less than 1 nanosecond. Femtosecond lasers go a step further and produce high quality ultrafast pulses in cycles from 30 femtoseconds to 800 femtoseconds. In the eyes of mankind, how short is this moment? One way is to compare the moment when the laser is open and closed. Conventional application models are typically 100 femtosecond laser pulses with a repetition rate of 100 kHz. If 100 femtoseconds are converted to 1 second, it is equivalent to the next pulse to occur after 3.5 years! Therefore, this effectively shortens the time at which heat affects the data to a minimum and maximizes the thermal release time of the data.
Compared to other types of lasers, femtosecond lasers have many advantages. The key is that the heat affected zone (HAZ) is usually smaller than a nanosecond or picosecond laser. Melting technology (known as cold-melting) without thermal damage in the surrounding area is designated for processing the scaffold and is also used to improve the strength and quality of cars and electronic products used in processing for mobile phones, tablets or wearable devices. When brittle materials such as hardened glass, this technique can minimize the formation of microcracks.
