‌‌The work on EUV lasers at YPI uses a capillary discharge in argon plasma to produce laser output at wavelength 46.9 nm.  Work is ongoing to develop the laser for the ablation of micro-features in solids and to understand the physics of the high density plasmas formed by EUV laser ablation.

Learn how to convert from mm to inches and what is the conversion factor as well as the conversion formula. 4.5 inches are equal to 0.177165 millimeters.

Deep depth of field. Set your f stop to a high number (for example, f/11). This will narrow your aperture, and you will let very little light into the lens. To ...

Extreme ultra-violet (EUV) light has many realised and potential applications. For example, the fastest computers chips are now processed using EUV light to expose photo-resist.  EUV light can be focused to widths approaching the wavelength of the light enabling small features in photoresist to be exposed.
