The laser unit is a dual head diode-pumped laser. The laser head is designed on a monolithic platform. Its energy per pulse is 30 mJ at 1kHz repetition rate, and the duration of a pulse is about 170 ns. The beam diameter is approximately 5 mm. The whole laser unit comprises of a chiller unit for cooling the laser head, two laser controllers, light arm and light sheet optics. This instrument is synchronized with a high frequency double exposure camera for time-resolved particle image velocimetry measurements in a fluid flow.
