Levante Emerald

Tunable OPO For Green Picosecond Lasers■

Levante Emerald is a widely tunable and fully automated NIR-OPO. The output wavelength ranges from640 nm to 2300 nm.

■

The OPO is adaptable to work with a green pump laser with pulse widths between 2 ... 20 ps and pumppowers from 2 ... 20 W.

■

The pulses are close to the transformation limit and are of high beam quality. The Levante Emerald has arobust mechanical design that offers stable long-term operation and excellent beam stability.

Automated Version■

The Levante Emerald offers full automation including software controlled tuning. This is made possible bystate-of-the-art control electronics, internal diagnostic systems and an intuitive software interface. ThePC control software is equipped with an additional command interface (via TCP/IP). This allows the OPO
to be easily integrated into larger test setups and software-controlled environments.

Wavelength Tuning■

The wavelength tuning is done by simply entering the desired wavelength into the Levante OPO controlsoftware. The actual wavelength and bandwidth of the OPO Signal is measured with an internal highresolution real-time spectrometer and the power is checked with calibrated photodiodes.

Tuning - Sweep Mode■

A sweep function is provided for fast tuning over a specific wavelength range. This enables automatictuning from a set initial wavelength to a set final wavelength in a very short time. Predefined hold times
for the spectral steps can be defined.

Multi-color Experiments & Multi-photon Microscopy■Signal and Idler are available simultaneously. Since they are collinearly radiated from the OPO, theSignal and Idler pulses show an intrinsically perfect spatial and temporal overlap at the output of thesystem. The photon energy difference between signal and Idler is continuously tunable, making theLevante Emerald an ideal system for multi-color excitation experiments such as SRS (Stimulated RamanScattering) or CARS (Coherent Anti-Stokes Raman Scattering).

-General Speciﬁcations
Signal and Idler Output

Signal and Idler are available at the same time; Both are coupled out collinearly of the OPO,
therefore the Signal and Idler pulses have an intrinsically perfect spatial and temporal overlap
in the output beam of the system; a removable beam separator is included

Time Bandwidth Producttyp. 0.6

Repetition Rate

~ 80 MHz (depending on the repetition rate of the pump laser)

Beam Quality M2< 1.2 (typ. 1.1)

Polarization

linear / horizontal

Wavelength Tuning

Fully automated for specified automated tuning range

Wavelength Tuning Feedback

Built-in diagnostics for wavelength (high-res spectrometer) and power (calibrated)

Sweep Function

Fast tuning over a certain wavelength range by sweep function; allows tuning from a set start
wavelength to a set end wavelength either with a predefined hold at each spectral step, orwith advance for each step on a software trigger.
