Introducing a femtosecond pulsed laser coupled to an optical parametric amplifier: a powerhouse for nanophotonics and quantum physics

Our group has installed a PHAROS femtosecond laser coupled to an I-OPA-HP optical parametric amplifier. The 1030 nm laser provides up to 0.4 mJ pulse energy and 20 W average power, with adjustable repetition rates up to 1 MHz. The I-OPA-HP offers wavelength tuning across 640–1010 nm (signal) and 1050–2600 nm (idler), with output pulse durations of 120–250 fs. An additional second-harmonic generation (SHG) module extends excitation into the ultraviolet, reaching approximately 300 nm. This versatile platform expands our capabilities for investigating ultrafast carrier dynamics, nonlinear optics, and light–matter interactions in emerging materials.
