Micro-Integrated ECDL-MOPA Laser Modules for Quantum Technology Applications — •Janpeter Hirsch, Martin Gärtner, Stephanie Gerken, Nora Goossen-Schmidt, Simon Kubitza, Norbert Müller, Max Schiemangk, Dian Zou, and Andreas Wicht — Ferdinand-Braun-Institut (FBH), Berlin, Germany

We present our next generation of micro-integrated ECDL-MOPA laser modules, each operating at a specific wavelength of 689, 767, 780, 794, and 922 nm, with adaptability to other wavelengths. The 767 nm module exemplifies their performance, delivering over 350 mW of fiber-coupled output power, a FWHM linewidth below 200 kHz at 1 ms timescales, and an extended mode-hop-free tuning range exceeding 100 GHz [1].

These modules are further designed with enhanced robustness to facilitate operation on mobile platforms and in space environments [2]. We will present results of preliminary mechanical stress testing, including shock tests at accelerations beyond 1000 g, to demonstrate their resilience and reliability under extreme conditions.

We acknowledge funding from Federal Ministry of Education and Research within the funding program "Quantum technologies - from basic research to market" under grant number 13N15724 and from DLR Space Administration / Federal Ministry for Economic Affairs and Climate Action under grant numbers 50WM2152, 50WM2176, 50WM2164, 50WM21694.
