Picophotonics lasers are diode-pumped solid-state microchip (DPSS) lasers incorporating proprietary semiconductor saturable absorber mirror (SESAM) technology for passive Q-switching. This approach allows pulse durations down to 50 ps, high repetition rates, and a narrow, stable spectrum, all within a robust, ultracompact package. The design offers excellent SWaP-C (Size, Weight, Power, and Cost), making it ideal for OEM integration while maintaining high optical performance suitable for industrial, analytical, and scientific applications.
Our microchip technology delivers significantly shorter pulses than typical industrial passively Q‑switched lasers, reaching down to 50 ps. This enables to higher peak powers, reduced thermal load, and enhanced resolution for time‑resolved spectroscopy, imaging, and precision sensing.
Our laser platform offers naturally a stable, mode-hop free, single-frequency spectrum (< 0.06 nm). This ensures precision and repeatability in demanding applications such as time-resolved spectroscopy and nonlinear processes.
SESAM-based Q-switching enables tunable repetition rates from single-shot up to several hundred kilohertz, without the need for external pulse pickers. This enables compact, cost-efficient integration into high-speed sensing and analytical systems.
Designed for industrial use, our platforms have demonstrated operation lifetimes exceeding 10,000 hours, delivering consistent performance and minimizing service downtimes.
Microchip technology provides an excellent size-to-performance ratio. Our patented laser design further enhances compactness without compromising optical stability or output quality, enabling seamless integration into portable and space-constrained instruments.
Our microchip platform brings picosecond performance to cost-sensitive markets, enabling integrators to deploy high-performance lasers in next-generation devices. European technology combined with scalable structure makes these lasers ideal for high volume applications.
In our Nanomagnetism & Nanophotonics Research Groups at Imperial, we have requirements for compact, power efficient, cost-effective and ultimately powerful & flexible pulse lasers - which were very challenging to meet all at once with a single device. We have been exceptionally impressed with the hardware, customer service, and value for money provided by Picophotonics products. The level of control, power, and pulse durations offered at a competitive pricepoint is extremely impressive - we have found roles for Picophotonics pulse lasers in all-optical nanomagnetic switching experiments, neuromorphic photonic neural networks, and a variety of other diverse & demanding nanoscale experimental avenues.
Picophotonics Team has been very helpful, creative, and we have already recommended their laser products to several collaborators who are also very happy with their purchase.
