Description
An ultra-compact 1029 nm nanosecond laser is a high peak power passive Q-Switch transmitter for OEM LiDAR and range finding applications. The short pulse duration of down to fewer than 1.3 ns allows high spatial resolution, the high peak power of >70 kW allows large distances to be measured.
Apart from LiDAR, this laser is also usable in portable or even wearable Laser-induced breakdown spectroscopy (LIBS) analyzers, portable and wearable LiDAR systems, and micro-scale material processing.
Current configurations in production:
| Variant | Pulse duration, ns | Pulse energy, μJ | Peak power, kW | Polarization |

Pulse-to-pulse stability of a uFlash laser
The video below shows superior pulse-to-pulse stability of a uFlash laser, operated at 50 Hz repetition rate, 120uJ pulse energy. The measurement was carried out using two different oscilloscopes and a fast 500 MHz bandwidth photodetector. The pulse duration of the laser was about 0.9 ns.
