产品介绍

The ASFL Series tunable sub-nanosecond lasers deliver dual-wavelength pulses with high repetition rate, narrow pulse width and high peak poweThese lasers provide 1064 nm and 532 nm outputs. Leveraging fiber-coupled diode end-pumping and diode-array side pumping, they achieve highly efficient solid-state amplification with outstanding thermal depolarization suppression, beam-quality control and damage resistance.Designed for 0–40 °C operation, they perform reliably on vehicle-, airborne- and ship-borne platforms. A modular architecture and universal components ensure easy maintenance of underlying parts. Typical applications include biomedical imaging, LiDAR point-cloud generation, laser ranging and atmospheric sensing.
