IR Opolette

The IR Opolette tunable laser system 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. All tunable beams exit the system from the same location resulting in one beam path to the end-user’s application. Wavelength tuning is hands-free and PC controlled. The system includes the Quantel Ultra Nd:YAG pump laser, OPO, access to 1064 nm pump beam, control software, SDK and 635 nm guidance laser to help with beam alignment.

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 IR 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

External Motorized Variable Attenuator

Vary the OPO pulse energy by choosing the external 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 energy stability. The MVA option connects through the electronics unit for computer control. Placement of the attenuator results in about 10% optical loss. If needed the MVA can also be removed for full energy access and reinstalled without need for alignment.

Option 5 Group

19" Rackmount Conversion

Choice of standard bench-top power supply and OPO control electronics box (default) or 19" rackmountable versions.

Option 6 Group

Software Development Kit

Software Development Kit (SDK) that allows end-users to integrate system control functions into third-party software can be downloaded for no charge. The SDK works under most Windows-based programming environments and provided with limited technical support.
