PicoQuant's compact and reliable turn-key diode laser solutions work in picosecond pulsed, modulated, or fast-switched (nsec to µsec) operation mode. The laser systems typically consist of a common driver unit and exchangeable heads. Specialized lasers are also available as stand-alone units. Use our laser product finder to find the suited laser for your application.
The picosecond pulsed diode laser drivers are designed as universal units that can control the dedicated laser or LED heads offered by PicoQuant. All drivers permit to control repetition rate and pulse energy of the attached heads. The drivers are available as single channel or multichannel units with manual or computer control. Their high quality and reliability are expressed by a unique 5-year limited warranty.
The picosecond pulsed sources are either laser diode based or LED based devices that can be operated at variable, user-adjustable repetition rates up to 100 MHz. They cover discrete wavelengths from 255 nm to 1990 nm. Power levels vary between µW and hundreds of mW for the most powerful, fibre amplified versions. Pulse widths can be as short as 40 ps.
These compact laser systems combine picosecond pulsed sources and versatile driving electronics into a single device. The most popular wavelengths from blue to red are thus available as easy-to-use, and affordable solutions.
The VisUV/VisIR lasers are a versatile and flexible laser platform based on a Master Oscillator Fiber Amplifier (MOFA) concept with optional frequency conversion. The stand-alone units emit picosecond pulses at repetition rates up to 80 MHz. Infrared versions with average powers up to 1.5W (VisIR) as well as units that emit in the ultraviolet at 266, 280, or 295 nm (VisUV) are available.
PicoQuant offers OEM laser solutions using the well-established technologies of its picosecond pulsed as well as square-shaped or pulse shaping lasers. Based on these technologies, PicoQuant can provide high-quality modules with custom designs and small footprints to meet the customer’s needs for large scale manufacturing or system integration.
All lasers from PicoQuant can be coupled into optical fibers, either individually or as a combination of up to five laser lines into a single fiber. Several types of delivery fibers are available, including single mode, polarization maintaining single mode and multimode ones. These fibers can be further equipped with various output connectors, collimation or even microfocus optics to best suit your application. In combination with the PDL 828 "Sepia II" driver, the Laser Combining Unit (LCU) offers an unmatched flexibility for multicolor excitation patterns.
Dedicated optical and electrical pulse generators capable of delivering nanosecond pulses for laser wavelengths ranging from 375 to 1550 nm as well as with programmable pulse shapes.

PicoQuant offers several modules for Time-Correlated Single Photon Counting (TCSPC), Multi-Channel Scaling (MCS), coincidence correlations, or event timing with temporal resolutions between picoseconds and milliseconds. Single channel as well as multichannel versions with either USB or PCIe interface can be provided. Their high quality and reliability are expressed by a unique 5-year limited warranty.
The available photon counting detectors include photomultiplier tubes (PMT), Hybrid photomultiplier tubes and Single Photon Avalanche Diodes (SPAD). The detectors cover different spectral ranges between the UV and the NIR and are optimized for time-resolved applications.
PicoQuant offers specialized software for the analysis of quantum correlations and fluorescence measurements. This includes multiexponential fluorescence decay fitting as well as special methods like FLIM and FLIM-FRET, FCS, FCCS, FLCS, anisotropy, antibunching, coincidences and the analysis of fluorescence time traces.
Accessories for photon counting experiments include a specialized dual channel power supply for SPADs, a signal delayer with picosecond resolution and a trigger diode. Signal conditioners (inverter, attenuator, pre-amplifier or splitter) as well as signal cables can also be provided.
PicoQuant designs and manufactures spectrometers that range from compact table-top spectrometers for teaching or daily routine work to modular high-end systems with exact timing down to a few picoseconds. Samples can be liquids in standard cuvettes, solid samples or even semiconductor wafers for in-line quality control.
PicoQuant’s fluorescence microscopes deliver high sensitivity and precision for applications like single-molecule detection, fluorescence lifetime imaging, and photoluminescence analysis. Combined with advanced software, they provide powerful tools for exploring dynamic molecular processes across various scientific fields.
PicoQuant offers advanced solutions for integrating sophisticated techniques such as Fluorescence Lifetime Imaging Microscopy (FLIM), Fluorescence Correlation Spectroscopy (FCS), and micro-Photoluminescence (micro-PL) into, e.g., widefield microscopes, laser scanning microscopes (LSMs), and spectrometers.
Science in Your Lab events are usually single day seminars co-organized by PicoQuant and a partner organization throughout the world. The events are aimed at introducing researchers to new techniques or methods in optical and single molecule spectroscopy or microscopy as well as to foster discussions between people from various scientific backgrounds.

Quantum optics is a field of research that deals with the application of quantum mechanics to phenomena involving light and its interactions with matter. One of the main goals is to understand the quantum nature of information and to learn how to formulate, manipulate, and process it using physical systems that operate on quantum mechanical principles.
Life Science refers to the fields of science that involve the scientific study of processes and structures of living organisms. While biology remains the centerpiece of the life sciences, related fields such as biochemistry, biophysics, or medicine are also included. Life science applications aim at understanding organisms and their place in the ecosystem.
Investigating the relationship between the atomic or molecular structure of materials and their macroscopic properties is a core aspect in the interdisciplinary field of materials science. The insights thus gained help in creating or modifying materials for improved performance. PicoQuant provides powerful tools like steady-state and time-resolved spectroscopy or microscopy to study a material’s excited state dynamics and processes. Coupling our fluorescence microscopes and spectrometers enables the acquisition of steady-state and time-resolved spectra from defined points or regions of interest in the sample. The resulting multidimensional datasets provide valuable new insights. Several combinations of different instruments are possible. Depending on the research question, one may be more suitable than others.
Metrology is the science of measurements. It refers to the process of measuring one or several specific parameters for a defined purpose. Metrology applications in this context are not directly related to specific research in life sciences or materials science, but are either generally applicable or serve a very specific measurement task.
