ORIGAMI IRO femtosecond optical parametric amplifier system

ORIGAMI IRO is a widely tunable, cost-effective femtosecond laser and optical parametric amplifier system. Get the industry-leading beam pointing stability and compactness of the air-cooled ORIGAMI XP and the ORIGAMI IRO's fully automated, environmentally stable OPA technology.

Cost-efficient femtosecond laser and OPA

The ORIGAMI IRO is an advanced Optical Parametric Amplifier (OPA) capable of providing widely tunable, multi-µJ fs pulses ranging from as short as 210 nm up to 11 µm.

Ideal for pump-probe spectroscopy and material characterization

The ORIGAMI IRO is designed for a diverse range of applications including optical material & device characterization, femtosecond pump-probe spectroscopy, time-resolved spectroscopy and photoluminescence (TR3, TRPES, TRPL), photoelectron-photoion coincidence spectrometry (PEPICO), coherent anti-stokes Raman spectroscopy (CARS), two-dimensional infrared spectroscopy (2D-IR), terahertz emission studies, and nonlinear microscopy.

Stable and reliable

The OPA is air-cooled and constructed with a sealed and monolithic case design and when coupled with industry-leading pointing stability of the ORIGAMI pump laser, allows for long-term stability and maintenance-free operation is possible.

Fully-automated and alignment-free

The ORIGAMI IRO covers a wide wavelength range spanning as wide as 210nm to 11 µm, while the integrated tuning makes automating experiments simple.

User-friendly by software and hardware design

No need for external beam routing or separation: the integrated tuning and automatic wavelength separation of the ORIGAMI IRO maintain the same beam position and pointing direction for all wavelengths.

Built-in monitoring and PC control

Onboard laser diagnostics and data logging ensures optimal performance and easy troubleshooting. Integrated PC simplifies control in your lab.
