The Family of Picosecond Nd:YAG Lasers

We developed an approach that ensures high shape stability of intense Nd:YAG laser pulses, based on a "microchip laser – regenerative amplifier" scheme. High-quality laser beam (M²<1.4) at 532 nm with 100-ps 2.5 mJ (RMS<1%) pulses was obtained at the repetition rates up to 1000 Hz. The reported architecture is flexible enough to design lasers that meet different requirements.
