Superhydrophobic surfaces attract a lot of attention due to many potential applications including anti-icing, anti-corrosion, self-cleaning or drag-reduction surfaces. Despite a list of attractive applications of superhydrophobic surfaces and demonstrated capability of lasers to produce them, the speed of laser micro and nanostructuring is still low with respect to many industry standards. Up-to-now, most promising multi-beam solutions can improve processing speed a hundred to a thousand times.

- There is a shortage of optical elements for mid-infrared wavelengths, especially when broad wavelength coverage is needed.
- A new polarizer design using uncoated silicon Brewster plates has been proposed, which includes a detailed analysis of performance factors such as contrast and reflections.
- The four-plate polarizer shows high contrast (over 10) across a wavelength range of 1.2-6.5 µm, making it a cost-effective and powerful solution for separating signal and idler beams in mid-infrared optical sources.
In ultrashort pulse amplification a narrowband gas pump pulse laser has been used for the first time. An all-stage optical parametric chirped pulse amplifier (OPCPA) was driven by a single-shot iodine photodissociation laser. For the first time a broadband amplification was achieved in potassium dihydrogen phosphate crystal at 800 nm seeding.
