Researchers show that using a laser writing technique called optical forging using​​ Light Conversion’s​​ PHAROS-10​​ increases graphene bending stiffness up to five orders of magnitude, opening venues for a plethora of new applications, such as GHz resonators and 3D scaffolds.

In a recent article, researchers at the Tritium Laboratory Karlsruhe (KIT) discuss how they used the​​ finesse laser​​ from​​ Laser Quantum​​ in their flagship experiment KATRIN (Karlsruhe​​ TRItium Neutrino mass). This experiment​​ employs high resolution​​ Raman​​ spectroscopy to deliver precise analysis of tritium-containing gases.

In a paper, entitled “Advantages of high-repetition-rate femtosecond lasers,” the authors conclude the following:

“Modern-day solid-state femtosecond lasers operating at multikilohertz repetition rates offer a unique combination of pulse energies high enough to produce almost​​ all nonlinear-optical phenomena​​ and, at the same time, they do it 10–100​​ times​​ faster than traditional CPA systems operated at 1 kHz or below. This results in unprecedented brightness of secondary radiation and helps to bypass the inherent fluence limitations imposed by the samples or detection systems. Together with the fact that these lasers are also more stable than their higher-energy counterparts, this makes them the tool of choice for modern research in spectroscopy, microscopy, nonlinear optics, and laser physics.”​​ 

Lasers of this type include the products of​​ Light Conversion.

Ultrafast laser-matter interaction has emerged as a highly universal platform with unprecedented optical phenomena and implementation paths for advanced manufacturing. Researchers report three-dimensional (3D) focal-area interference patterning in transparent dielectrics using Light Conversion’s​​ PHAROS laser.
