QUBIG GmbH is a technology company in the field of laser conditioning with a focus on the development and manufacturing of laser light modulators as well as suitable driver electronics up to >40 GHz. The devices are mainly installed as subcomponents in larger systems, with the aim of quickly and precisely controlling the properties of the laser light, such as its frequency, phase, polarisation and position.

Main activities

• manufacturing of high-quality electro-optical modulators (EOM) for free-space lasers and special phase- and amplitude-modulators
• development of application specific EOMs for Laser/Cavity frequency stabilization (PDH lock), laser spectroscopy, laser cooling, and spectral broadening
• development of compatible RF drivers based on DDS: stable, flexible and targeted for applications like laser locking, as well as suitable photodiodes

Services

• Resonant, tuneable and broadband EOMs in the kHz - GHz frequency range tailored for laser locking and
• spectroscopy
• High power EOMs for intense lasers with large aperture and high optical damage threshold, e.g. for spectral
• broadening
• Custom specific development of EOMs, e.g. for UV wavelength, temperature stabilized and fibre coupled models
