In 1999, the Nobel Prize in Chemistry was awarded to Professor Ahmed Zewail for his achievements in the analysis of chemical reaction in ultra-short time. Within a decade, from the development of a new technology to the application of the technology and the Nobel Prize, this demonstrates the revolutionary changes that ultrafast lasers bring to science.
In the past decade, the potential of ultrafast lasers in new industrial or medical applications has become apparent, even though lasers at the time failed to meet the performance, cost, specification, and reliability requirements of various industries.
Around 2000, a new generation of diode-pumped ultrafast lasers using erbium-doped laser materials and carrier-grade semiconductors was introduced to the market. These compact, high-power, highly reliable, and cost-effective ultrafast laser sources expand industrial applications for the rapidly expanding market. As a result, the number of installations has doubled over the past decade.
Today, the industry is able to offer commercial industrial ultrafast lasers with a wide range of pulse widths from femtosecond to picosecond, with an average power range of tens of watts for demanding industrial and medical environments.
Application background
Ultrafast lasers concentrate pulse energy in a very short time, resulting in extremely high power density. The compact desktop ultrafast lasers provide power even beyond nuclear power plants. Thanks to such high power, its laser can process almost any type of material, including traditional, difficult-to-machine materials such as metals, ceramics and glass.
In addition, since the pulse width is extremely small, almost no excess heat is generated during processing, and the effect and quality of such athermal processing are excellent. In addition, there is no melting, cracking, vaporization or other harmful heat dissipation during micromachining.
Ultrafast lasers are now being used in industrial applications where high quality machining results are sought, such as:
â— Selective ablation for processing thin films used in semiconductor, display or photovoltaic industries;
â— Stress-free engraving for anti-counterfeiting applications in the pharmaceutical and luxury industries;
â— Eye refractive surgery, including vision correction and cataract surgery;
â— High quality micromachining applications in the microelectronics industry;
â— Medical equipment manufacturing.
