The Opium, an ultrafast optical parametric oscillator that provides continuous tuning from the visible to the near-UV with a single set of optics, has been unveiled by Radiantis. The synchronously pumped device produces femtosecond near-transform-limited pulses. A frequency doubler provides tuning from 350 to 700 nm. Four separate output wavelength ranges are also available: visible, 500 to 700 nm; UV, 350 to 450 nm; near-IR, 700 to 900 nm and IR, 900 to 2200 nm. The device, which measures 360 × 954 × 230 mm, has an average signal output power of ∼150 mW.
