Product Description

Levante Emerald Picosecond (ps) is a widely tunable fully automated high power near infrared (NIR) optical parametric oscillator (OPO) of ps pulses. It is based on a synchronously pumped OPO, with an external green ps laser as pump.

The OPO is adaptable to work with pump pulse widths between 2 to more than 20ps and pump powers from 2 to 20W for an output power of up to W. The pulses of the output beams are close to transform limit and of high beam quality. The Levante Emerald Picosecond exhibits a robust mechanical design on a solid steel baseplate enabling stable long term operation as well as excellent beam pointing stability.

The Levante Emerald Picosecond has been newly developed featuring full automation, i.e. software controlled tuning. This is made possible by its entirely new control electronics, internal diagnostics, and control software packaged conveniently in a new housing. Hence handling has never been easier. The control software on the computer is equipped with a software interface. The OPO can easily be integrated into larger experimental setups and software controlled environments. The new Levante Emerald Picosecond is based on APEs long standing experience in developing and manufacturing fully automated OPOs.

APE have a complementary range of laser diagnostic equipment for complete laser characterisation of ps and femtosecond laser pulses including autocorrelators, pulse pickers and SPIDERS.

  • Fully automated tuning
  • 2ps or 6ps or 15ps versions
  • Control software: simply enter the desired wavelength
  • Internal diagnostics for power and wavelength
  • Two tunable output beams with different colors (signal and idler)
