APE Levante Emerald ps Tunable NIR OPO

Tunable automated ps NIR OPO suitable for an external green ps pump laser

APE

The Levante Emerald is a widely tunable fully automated high power NIR OPO of ps pulses. It is based on a synchronously pumped optical parametric oscillator (OPO), with an external green ps laser as pump. The OPO is adaptable to work with pump pulse widths between 2 ... > 20ps and pump powers from 2 ... 20 W for an output power of up to 6W. The pulses of the output beams are close to transform limit and of high beam quality. The Levante Emerald exhibits a robust mechanical design on a solid steel baseplate enabling stable long term operation as well as excellent beam pointing stability.

 

Features:

  • Fully automated tuning
  • 2ps or 6ps or 15ps version
  • Control software: simply enter the desired wavelength
  • Internal diagnostics for power and wavelength
  • Two tunable output beams with different colours (Signal and Idler)
  • Signal and Idler beam overlapped in space and time  |  Beam separator included
  • Ideal 2ps pulse width for CARS, Coherent Raman imaging
  • Remote access available for customer support and error diagnosis

The Levante Emerald 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 PC is equipped with a Software Interface (using TCP/IP). The OPO can easily be integrated into larger experimental setups and software controlled environments. The new Levante Emerald is based on APEs long standing experience in developing and manufacturing fully automated OPOs.

 

Because of the synchronous pumping, the Signal and Idler pulses of the Levante Emerald are generated jitter-free with respect to each other as well as the pump pulse. Since they are coupled out of the OPO collinearly, the Signal and Idler pulse have an intrinsically perfect spatial and temporal overlap in the output beam of the system.

 

The photon energy difference between Signal and Idler is continuously tunable, which makes the Levante Emerald an ideal system for multi-color excitation experiments, such as e.g. SRS (Simulated Raman Scattering), or CARS (Coherent Antistokes Raman Scattering).

 

Using a pump laser which offers also (preferably undepleted) fundamental pulses of 1064 nm, or similar, even more combinations of jitter-free pulses with different wavelengths are available.

 

The Levante Emerald 2ps (pumped by the Emerald Engine with 2 ps pulses) offers an optimised pulse width with maximum spectral bandwidth in the Raman fingerprint region without compromise in resolution for highest signal levels. Its high efficiency in non-linear processes makes the Levante Emerald 2ps an ideal tool for applications such as CARS (Coherent Antistokes Raman Scattering) and SRS (Stimulated Raman Scattering) imaging applications. Compared to the 6ps version of the Levante Emerald, the Levante Emerald 2ps has shown improvement in CARS signals by a factor of 10, and in SRS signals by a factor of 2.5. Also signals of SHG or Multi Photon Fluorescence are much improved. The Levante Emerald has been successfully used for SHG imaging. Important wavelengths for MPE (Multiphoton Excitation Microscopy) are directly available, such as e.g. 950nm for GFP (green fluorescence protein) or 1160 nm for RFP (red fluorescence protein).
