Photonics Industries Introduces the Highest Pulse Energy YLF Ultraviolet Lasers Available

10/28/2014

(Bohemia, NY - Aug 27, 2014) - Photonics Industries (PI), The Pioneer of Intracavity Solid-State Harmonic Lasers, was the first to develop high efficiency Q-switched, intracavity second harmonic Nd:YLF green pump lasers back in 1993. PI continues to lead this technology with the introduction of our new DM20-351, the highest pulse energy Ultraviolet (UV) laser:

Over 20mJ @ 1kHz

commercially available with the same excellent beam quality (i.e., M2 ~10) of our green DM Series laser. Furthermore this high pulse energy is scalable to 40mJ in a dual head configuration for applications ranging from UV induced fluorescence, Particle Image Velocimetry (PIV) to annealing semiconductor materials for the flat panel display industry.

Annealing of the larger and more uniform grains of polysilicon (poly-Si) in Low Temperature PolySilicon (LTPS) LCDs allows electrons to flow ~100 times faster (i.e., annealing improves resistivity) than these electrons can through the random-sized grains of amorphous silicon (a-Si), enabling higher resolutions and higher speed flat panel display. While 308nm XeCl Excimer lasers are typically used today for this OLED annealing, other wavelength (e.g., 351nm) can used. UV induced fluorescence applications need high pulse energy UV lasers to induce fluorescence to test the spectrum of gas combustion process in engine research.

PI's product roadmap is based on customer needs. For example the PIV community has been inquiring about moving from visible (i.e., green) to UV wavelengths. Twin pulses are often required for vectoral mapping of the PIV flow fields. With a single DM20-351 laser, by using PI's patented twin pulse feature, you can now get twin UV pulse of ~10mJ each from a single laser head.
