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 >100 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.
| Variant | Pulse duration, ns | Pulse energy, µJ | Peak power, kW | Polarization |
|---|---|---|---|---|
| 1 | 1.3 | 150 | 115 | Random |
Other parameters can be developed based on customer specifications. Please refer to the specifications table below for possible parameter ranges.

Dimensional drawing of the uFlash laser.

The video below shows superior pulse-to-pulse stability of a uFlash laser, operated at 50 Hz repetition rate, 120 µJ 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.

Applications

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.

Laser Rangefinding

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.

LIBS(Laser Induced Breakdown Spectroscopy) stands for laser-induced breakdown spectroscopy
and is a rapid chemical analysis technique, first introduced in 1960s. Unlike in Raman spectroscopy,
it uses short laser pulses to create plasma plumes on the surface of a sample and
the spectrum is characterized of this plasma using low-cost spectrometers.
It is also categorized as an in situ operation, that’s duration can last up to only a few seconds.
