An Essential Guide To Femtosecond Laser Micromachining That You Should Know About

Femtosecond laser micromachining utilizes systems that emit optical pulses of infrared (IR) laser light with durations in the femtosecond range. Electro-magnetic pulses with a duration of picoseconds or less are categorized as ultrashort pulses, which generally present high powers on megawatts (MW) or more and high pulse repetition frequencies.

A type of optical amplification, such as chirped pulse amplification (CPA) must be used for achieving high peak femtosecond laser pulses. It is a system used to amplify ultrashort laser pulses and leads to peak power, reaching petawatts. All high-performance femtosecond lasers use a CPA variant to deliver high peak output with high-repeat ultrashort lasers.

Types of Femtosecond Lasers

The multiple parameters of femtosecond lasers (for example, gain, bandwidth, output frequency, etc.) need to be regulated by the CPA. Mode-locking refers to technologies that monitor these lasers’ parameters and produce powerful laser light pulses of high quality. The varieties of mode-locked lasers competent of producing high-intensity femtosecond pulses of light include:

· Solid-state bulk lasers

· Fiber

· Dye lasers

· Semiconductor lasers

Femtosecond Laser Applications

Femtosecond laser applications currently affect a broad range of sectors ranging from pharmaceutical to microscale machining. Femtosecond laser micromachining has demonstrated outstanding potential for ultra-precise joining of difficult materials such as transparent media, including glass-to-glass welding.
