The picosecond laser is a laser with a pulse width of picosecond. It has picosecond ultra-short pulse width, adjustable repetition frequency, and high pulse energy. It has more and more extensive applications in the fields of biomedicine, optical parametric oscillation, and biological micro-imaging, and has gradually become a modern biological imaging and analysis system. Increasingly important tools.

A semiconductor diode laser with a wavelength of 980 nm.
