Microfabrication, research and development, industrial high-power ultrashort pulse laser PHAROS

Simultaneously achieving high output and high energy of femtosecond lasers enables high-quality, high-precision fine processing at high speed due to high repetition operation and stable emission direction.

Excellent beam quality, stability of emission direction, and low running costs make it ideal for microfabrication and micromachining. Equipped with pulse width and output variable functions, as well as pulse-on-demand capabilities, it allows for easy changes to laser irradiation conditions, making it perfect for application development and equipment integration. Additionally, leveraging high pulse repetition frequency and high average output contributes to improved S/N and significant reductions in measurement time, benefiting the fields of physics and research and development. By combining PHAROS (high average output of 20W @ 1MHz) with ORPHEUS (OPA) and wavelength extension units, it enables wavelength variability up to 16μm, making it suitable for spectral analysis and more. Furthermore, high output and high energy types (20W, 4mJ/pulse @ 3kHz) and ultra-short pulse width types (>100fs) have been added, making it ideal for various processing, application development, and equipment integration. A high-output ultra-short pulse (femtosecond) laser has achieved significant miniaturization and low power consumption through direct excitation of laser diodes. It features pulse width and output variable functions, as well as pulse-on-demand capabilities, allowing for easy changes to laser irradiation conditions.

What is a ultrashort pulse laser?

Lasers with pulse durations on the order of picoseconds (10^-12 seconds) or femtoseconds (10^-15 seconds) are called ultrashort pulse lasers.

Among laser light, those that repeatedly blink at short intervals are called "pulse lasers." Among them, lasers with a short emission time (duration), particularly those in the pico (10^-12) second or femto (10^-15) second range, are referred to as ultra-short pulse lasers. The processing technology developed by later Nobel Prize-winning techniques In 2018, Dr. Gérard Mourou and Dr. Donna Strickland, who devised and demonstrated a method called CPA (Chirped Pulse Amplification), were awarded the Nobel Prize in Physics. This was 33 years after the first paper was published in 1985. While the details are omitted here, this technology significantly contributed to the development of short pulse and high intensity in pulse lasers. By the 1990s, ultra-short pulse laser processing began to be actively researched in research institutions around the world. From the 2010s, fiber laser-excited ultra-short pulse lasers became commercially available as industrial lasers. The laser oscillators we have introduced are these industrial picosecond and femtosecond lasers.

Passive Q-switch picosecond laser

This is a sub-nanosecond microchip laser with a simple structure that covers a wide range of wavelengths from small, low-cost IR (1550nm) to DUV (213nm).

We specialize in fine processing with minimal thermal impact using short pulses. Despite high output, it is adopted in analyzers as an alternative to flash lamp-excited lasers and as a substitute for expensive CW-type UV lasers, while maintaining low noise. 【Application Examples】 - Glass marking - Microdissection of biological cells - Diffraction color marking - Laser-excited fluorescence analysis - PCB repair - Multiphoton excitation - FPD repair - Gas sensing - Fine processing - Temperature sensing For more details, please contact us or download the catalog.
