Picosecond laser as a new energy source, has a picosecond level ultrashort pulse width, repetition frequency adjustable, high pulse energy, etc, in biomedical, optical parametric oscillation, biological microscopic imaging, and other fields have more and more widely used, has become increasingly important in modern biological imaging and analysis system for tool.

 

 

With the continuous development of laser technology, the research of interaction between laser and organism, laser is widely application in biomedical. Especially the picosecond laser has been widely applied in biological analysis of imaging and optical measurement, and other fields, including: fluorescence microscope, CARS, imaging, medical diagnosis and treatment, STED microscopy imaging, etc.

The SPARK LASERS picosecond laser in typical applications in the field of biological photon

1. SPARK LASERS series of ANTARES picosecond laser based on its high average power, peak power, narrow linewidth, up to 80 MHz, compact volume, pulse repetition frequency optional, wavelength, optional (green, uv) wait for a characteristic, has the following main application direction:

OPO pump: using the peak power and narrow linewidth
