[ Light Conversion ] Enhanced mid-IR output with ORPHEUS-ONE OPA

13 Mar, 2015
ORPHEUS-ONE is a collinear optical parametric amplifier of white-light continuum pumped by femtosecond Ytterbium based laser amplifiers. This OPA is focused on generating the mid-infrared wavelengths and maintains the excellent output beam properties of a standard ORPHEUS. 
Parametric amplification is performed in two stages. The first nonlinear crystal is pumped with the second harmonic of pump laser at 515 nm and seeded with a white light continuum, which generates a very stable tunable output in two ranges: 650 nm - 850 nm (first stage signal) and 1350 nm – 2100 nm (first stage idler). The second nonlinear crystal is pumped by the fundamental pump radiation at 1030 nm, and seeded with the idler of the first stage. The output of the second stage is a Signal wave tunable in the range of 1350 nm – 2060 nm, and corresponding Idler at 2060 nm – 4500 nm.
