The PM8-NIR from QUBIG is a Lithium Niobate (LiNbO3) Electro-Optic Phase Modulator that operates at a wavelength of 630 nm - 1200 nm. It has a resonance frequency of 42.1 MHz - 57.6 MHz and an operating bandwidth of 361 kHz. This electro-optic phase modulator has a quality factor of 139 and an aperture size of 3 mm x 3mm. It has a wavelength distortion of lambda/6 (at 633 nm) and an optical intensity of up to 1 W/mm2. This electro-optic phase modulator has a preset frequency of 50 MHz and an AR coating with a reflectance of 1% & transmittance of 98%.
The PM8-NIR features damped piezo- and acoustic resonances with low residual amplitude modulation (RAM) options. It requires an RF power of 18.2 dBm (for 1 rad at 960 nm) and a maximum RF power of 1 W. This electro-optic phase modulator is available in a housing that measures 40 (L) mm x 40 (W) mm x 40 (H) mm and is ideal for laser frequency stabilization (PDH, FM/MTS), laser cooling / repumper generation, quantum state manipulation, spectroscopy, and spectral broadening applications.
