Opolette 2731/3034

The Opolette 2731/3034 tunable laser series utilizes optical parametric oscillator (OPO) technology to generate wavelengths over a broad range in the MIR. Designed for portability, the entire laserhead fits into a 7x12” footprint and ships completely sealed to protect optical components from the environment. Requiring no installation, the system includes verification hardware to check alignment after shipping or relocation. A built-in red laser diode is aligned to overlap with the mid-IR output for beam guidance. Wavelength tuning is motorized and computer controlled.

Build Your Product
Option 1 Group

Wavelength Range

Choose between two wavelength ranges based on the OPO crystal material. Only one wavelength range available for each system.

Option 2 Group

Energy Level

The Opolette can be configured for two energy levels, as presented in the tuning graphs. Select the desired configuration based on the graph. The outside dimensions are identical.

Option 3 Group

Harmonic Addition

Add second and third harmonics to the system to convert residual 1064 nm into 532/355 nm wavelength access. The 355 nm wavelength exits a separate front port in the system and the 1064/532 nm both exit the same port in the front of the system.

Option 4 Group

Motorized Variable Attenuator

Vary the OPO pulse energy by choosing the Motorized Variable Attenuator (MVA) option. By default the end-user changes the OPO pulse energy by changing the pump laser pulse energy through software command. However, OPO pulse-pulse energy instability increases at lower pump laser energy levels. The MVA option involves maintaining the pump laser pulse energy at maximum and using optical attenuation to change the OPO pulse energy without compromising pulse energy stability. The MVA option connects through the electronics unit for computer control. The MVA option is external and therefore can  be removed for full OPO pulse energy access. It can be reinstalled without need for alignment.

Option 5 Group

Protective Hard Case

The Opolette is designed for portability which allows the end-user to move the system to different locations. The standard wooden shipping crate can be replaced with two protective hard cases with custom foam padding to facilitate packing and moving the system between locations.
