Nd:YLF High-Frequency Dual-Pulse Green PIV Laser
For time-resolved PIV measurements (TR-PIV) of unsteady flow fields, we offer the kHz high repetition rate Vlite-Hi-527 dual-pulse green laser.
To achieve high repetition rates and high pulse energy, the Vlite-Hi-527 laser utilizes LD-pumped Nd:YLF laser crystals, acousto-optic Q-switched technology, and intracavity frequency doubling technology. It provides highly stable pulse energy ranging from 20mJ to 60mJ @ 1kHz, with an adjustable repetition rate of 0.2kHz to 10kHz.
In terms of design, the Vlite-Hi-527 features a unique optical path design and engineered technology to ensure operational stability, with energy output stability less than 1%. As a Class IV laser, the Vlite-Hi-527 series places special emphasis on safety and electromagnetic compatibility design. It is equipped with protective shutters, built-in interlocks, flow switches, emergency stop switches, and enclosure protection switches to provide comprehensive safety for users and equipment. This series of lasers obtained CE certification in 2020.
