Description

A sealed, hands-free and fully-automated femtosecond optical parametric oscillator (OPO) that offers class-leading wavelength coverage with high average power in the near- and mid-IR. Compatible with standard femtosecond MHz repetition rate Ti:sapphire oscillators, the Oria IR is an ideal tool for nonlinear microscopy applications where short pulse durations, high beam pointing and high power stability are required in the IR.

The Oria IR is a femtosecond OPO, pumped by a mode-locked femtosecond Ti:Sapphire oscillator, which offers broad tunability in the near- and mid-IR. Independent tuning of the pump wavelength across 720 – 810 nm (12195 – 14084 cm^-1), and the signal wavelength across 1000-1580 nm (6329 – 10000 cm^-1), is provided through the two separate pump and signal output ports available in this OPO. The user can easily select amongst accessing: (i) 100% of the pump through the pump output port, with no signal through the signal port, (ii) a percentage of the pump through the pump output port, with partial signal through the signal output port, or (iii) 0% of the pump through the pump output port, with full signal through the signal output port.

As a sealed system, the Oria IR does not provide user access to the internal cavity. Absolutely hands-free operation is guaranteed, with manual alignment of the OPO neither possible nor required. Tuning across the range can be readily achieved within a few seconds, by controlling the system exclusively via a simple and dedicated PC-user-interface.

The Oria IR delivers unique conversion efficiency performance, resulting in high power levels across the wavelength range. Also, near-transform-limited pulses, excellent power stability and exceptional beam quality across the tuning range are provided.

The Oria IR is a USB compatible and compact system formed by a single optics unit (395 x 703 x 192 mm), which does not require additional bulky external units such as chillers or MRU air recirculators. A portable and ready installed computer is also available with this OPO.

The Oria IR is provided directly by Radiantis^®.
