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.
Please note, that this product is laser-head-only for OEM. Driver electronics and pulse generator come separately within µFlash Integrator's kit (contact Integrated Optics support for more info) or can be implemented by end-user.

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.

Flash LiDAR

Flash LiDAR is an advanced remote sensing technology that utilizes laser pulses in a rapid, sweeping fashion to create high-resolution 3D maps of the surroundings. Unlike traditional Lidar systems that rely on scanning mechanisms, Flash Lidar captures the entire scene simultaneously, providing real-time and comprehensive spatial information. This innovative approach enhances the speed and efficiency of mapping, making Flash Lidar well-suited for applications in autonomous vehicles, robotics, and environmental monitoring.

Photoacoustic imaging

Photoacoustic imaging is a process where powerful laser pulses interact with material by exciting acoustic waves. Similarly, as in ultrasound imaging, the propagating acoustic waves are analyzed by piezo-based detectors (pick-ups), and the complete 3D image is formed by raster scanning or other techniques, such as laser-based holography or interferometry.
