High-Speed Holographic Microscopy

The high-speed impact of a droplet on a bulk fluid at high Weber number is not well understood but is relevant to the production of marine aerosol by raindrop impact on the sea surface. These splashes produce a subsurface cavity and a crown which closes into a bubble canopy, but a floating layer of immiscible oil, such as a crude oil slick, alters the splash dynamics.

EMPT Welding

With the help of a special image intensifier camera and a laser, which illuminates the joint area, a new attempt is made to visualize the impact in electromagnetic pulse welding.

Laser Welding

Filming the welding process is accompanied by an additional obstacle in addition to the high-speeds: During this process, a bright light covers the actual joint area. The bright process glare can be suppressed by a trick. As the glare is usually whitely, it can be concluded that its intensity is spread almost constantly across all (visible) wavelengths.

Fiber Laser Mode Instabilities

The temporal behavior of mode instabilities in active large mode area fibers is experimentally investigated in detail. Thus, apart from the onset threshold of mode instabilities, the output beam is characterized using both high-speed camera measurements with 20,000 frames per second and photodiode traces.
