1030 nm Nanosecond Q-Switch Laser

Item Code:
Product status:
Preliminary Product specifications are subject to change, delivery time is less predictable.

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.

Current configurations in production:

1 Peak power limitations apply. Max. peak power currently is 300 kW in for unpolarized radiation and 100 kW for polarized radiation. We put constant R&D efforts to increase this further.
2 The laser is not collimated internally.
3 A demo electronics board is provided with the first order of 5 pcs.
4 Only laser head.
5 e.g. 1W @20Hz pulse repetition rate in single-pulse triggering mode.
6 Warranty is not applicable to faults of the pump laser diode - a component which is sensitive to electronics circuitry design and operational regimes. Please consult with Integrated Optics regarding most appropriate driving circuit design, duty cycles, etc.

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.
