OPO Levante IR
Data Sheet

The Levante Emerald is an optical parametric oscillator (OPO) synchronously pumped by a frequency doubled solid state laser. The Levante Emerald is pumped by a Nd:YVO laser at 532 nm and offers a Signal wavelength range from 1150 to 2300 nm.

With the Levante Emerald a stable system with broadband tunable ps- or fs-pulses is available offering high average power in the NIR and excellent beam pointing stability. The generated pulses are bandwidth limited and of high beam quality. Tuning of the wavelength is easy and computer controlled.

A complete new beam quality is reached with the intrinsic perfect spatial and time overlap of the Signal and Idler beam, which are collinearly coupled out of the system. The generation of the Signal and Idler pulses in a parametric process is jitter free with respect to each other as well as to the pump pulse.

The energy difference between Signal and Idler is continuously tunable, which makes it an ideal system for multi color excitation experiments, such as e.g. coherent Raman Scattering or CARS (Coherent Anti-Stokes Raman Scattering). Important wavelengths for MPE (Multiphoton Excitation Microscopy) are supplied directly from the system, such as e.g. 950 nm for GFP (green fluorescence protein) or 1160 nm for RFP (red fluorescence protein).

Features
  • Two tuneable output beams with different colours (Signal and Idler)
  • Jitterfree generation of different wavelengths
  • Integrated spectrometer for the Signal range
  • Automatic tuning of wavelength via PC-software
  • Signal and Idler beam separator included in case both beams are needed from separate outputs
