• Autocorrelators
• Pulse quality detectors
• Laser radiation detectors
• Spectrometers

Equipment for measuring laser pulses in the widest range from UV to far infrared from 200 nm to 12 µm and a wide pulse duration range from 5 fs to 500 ps. In addition to pulse width and pulse shape measurements, we also offer phase detection instruments with the user-friendly FROG and SPIDER technologies.

High-contrast measurements provide information on how far in time and intensity the main pulse is accompanied by pre-, post- and pedestal pulses.

Some models have a high dynamic range of 107, which is ideal for characterizing high-intensity laser pulses with high repetition rates, such as those used in materials processing or ultra-high intensity light-matter interaction experiments.

Rotating grating spectrometer. This technology allows it to cover a wide wavelength range from 200 nm to 6300 nm. A quick and easily replaceable input port allows WaveScan to be adapted to free space or fiber lasers and can be remotely controlled via USB or TCP/IP.

• Dual-color SRS with deltaEmerald
• Tunable picosecond laser
• Tunable diode-pumped nanosecond laser source
• Broadband mid-infrared light source
• OPO / OPA
• Harmonic and difference frequency generation

Innovative SRS circuit for simultaneous excitation of two oscillating bands, with tunable pumping and overlapping spatiotemporal stokes pulses.

The picoEmerald picosecond laser emits ultrashort pulses of 2 ps duration (other durations are possible). The wavelength tuning of the picosecond laser is fully automated in the tuning range from 700 nm to 990 nm and from 1080 nm to 1950 nm. A main beam mode with a wavelength of 1032 nm is also available. A scan/sweep function is also provided.

The mid-IR tunable broadband light source is fully automated, allowing for customized, off-the-shelf solutions. At the core is a 1 µm pump laser operating at 76 MHz, which drives an optical parametric oscillator (OPO).

• Acousto-optic switch
• Monochromator
• Optical delay line
• EOM / AOM

The range of pulse signal processing equipment includes:

Dispersion Compensation Module. Femtosecond pulses passing through any optical material experience dispersion, which can lead to temporal broadening of ultra-short pulses with a consequent reduction in peak power. FemtoControl compensates for material dispersion by imposing the inverse of the dispersion on the pulse.

An acousto-optic switch that can be integrated into the resonator of a mode-locked laser system to reduce the pulse repetition rate of the system.

Standard laser sources only generate fixed or weakly variable pulses, so the pulseSlicer monochromator works as a device to isolate a specific region of the spectrum and is a cost-effective solution for narrowing broadband laser pulses.

ScanDelay is an optical delay line that generates both fast wideband scans and tiny delays without slippage effects.

• Picosecond laser for control of quantum dot emission process
• Tunable femtosecond-laser system for calibration of reference solar cells
• CARS & SRS
• ARPES

The tunable femtosecond-laser system avoids the main problems of traditional approaches: the low optical power level of monochromatic sources and the wide spectral range of LED-based systems. The new femtosecond-laser system enables calibration of reference solar cells on the World Photovoltaic Scale (WPVS) with an error of only 0.4%, which is a new world record.

The combination of the tunable picosecond-laser piso and ARE's pulseSlicer monochromator enables resonant excitation of the quantum dot emitter with very high efficiency without background radiation.

The laser ARPES operates with a narrowband UV laser source that provides a consistently high photon flux with extremely high energy resolution down to 0.1 meV.
