Researchers from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU), in collaboration with scientists from the Consejo Superior de Investigaciones Científicas (CSIC) and the Universidad Complutense de Madrid have developed a new laser material which improves the use of light in biophotonics, making it more efficient and longer lasting by incorporating dye molecules.

A new optical technique, capable of producing laser beams with unusual modes of electric field, has been developed by scientists at the University of Liverpool. The new technique could have a major impact on laser micro-machining, by increasing process efficiency and quality through the use of different modes of ‘polarisation' or electric fields. These are unusual states of light and difficult to produce.

For the first time, researchers have produced a coherent, laser-like, directed beam of light that simultaneously streams ultraviolet light, X-rays and all wavelengths in between (see video). One of the few light sources to successfully produce a coherent beam that includes X-rays, this new technology is the first to do so using a setup that fits on a laboratory table.

PicoQuant has added two laser heads emitting at 395 nm and 420 nm to its LDH Series.
Both laser heads are ideal for exciting e.g. porphyrin or phthalocyanin containing samples in fluorescence microscopy or fluorescence spectroscopy. With pulse durations as short as 70 ps, they are match the time resolution of mainstream detectors, yet at a price much lower than of mode-locked lasers or nanosecond flashlamps. The two laser heads are also available in a dual mode version that allows picosecond pulsed as well as continuous-wave operation.
