Researchers Develop an Optical Toolbox to Build Low-Cost Microscopes

Modern microscopes used for biological imaging are expensive, are located in specialized laboratories and require highly qualified staff. To research novel, creative approaches to address urgent scientific issues -- for example in the fight against infectious diseases such as Covid-19 -- is thus primarily reserved for scientists at well-equipped research institutions in rich countries.

A New Solution to Create Strong, Short Laser Pulses

Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared lasers are much more difficult to manufacture, especially if the laser radiation is required in the form of extremely short, intense pulses.
