Picoquant has released a 485 nm picosecond pulsed diode laser head. The availability of this new wavelength opens the door for entirely new applications in bioanalytics, biochemistry, genetics, semiconductor characterisation and quality control. The new laser head is ideal for exciting fluorescent proteins like GFP and widely used fluorescent dyes such as Fluorescein, Atto 488 or Alexa 488 and fills an urgent demand for alternatives to frequency doubled solid state lasers or argon-ion lasers in applications like Fluorescence Microscopy.
