In the development process towards an integration of laser systems into compact modules many key points can be simulated. Yet, a reliable and stable testing environment is needed for a deeper understanding of the system. We present the micro optical bench (MiOB) as an advanced platform for the hybrid micro integration of active and passive optical elements. The modular yet robust design enables the precise mounting of those elements with an accuracy of better than 1 µm. By examples of second harmonic generation, master oscillator power amplifier and external cavity diode laser modules a wide range of applications are addressed. Each module is used to highlight different aspects of the MiOB. Examples are the thermal design of the MiOB that allows the precise heating of selected components without influencing others, the robustness that can withstand different mechanical tests, and the overall stiffness that allows the high precision mounting of volume holographic Bragg gratings.
