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 7×12” 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.
