The research is now picking up speed thanks to the joint project DioHELIOS within the “Fusion 2040” funding program. It ...

laser-diode modules that provide 100 W of power out of a 400-μm-core fibre can be produced, with a numerical aperture of 0.22. Such 100-W modules can be cooled using only forced air or peltier ...

Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...

Abstract: Early studies suggest that absorption coefficient of GaN exceeds 100 cm ⁻¹ at wavelengths below 380 nm, indicating GaN might not be suitable as a waveguide (WG) material for laser diodes ...

Most light emitting diodes function in the near infrared and visible ranges, though there are now UV LEDs as well. Tunnel diodes are heavily doped P-N diodes in which electron tunneling from the ...

Results from PV testing laboratories in 2024 have raised concern over ultraviolet-induced degradation (UVID) in some n-type TOPCon and HJT panels. The “PV Module Index Report” from the Renewable ...

What is a Diode Array Detector? A diode array detector is a detector that absorbs light within UV or visible wavelength spectrums to perform spectroscopic scanning and to obtain precise absorbance ...

If we figure out how to harness this effectively and efficiently, this is it. This is the end. This is the solution,” an expert tells us.

In LASIK, an ultraviolet laser called an excimer removes parts of the cornea with extreme precision, changing its shape and how light travels through it to the retina. Lasers are useful in ...
