Abstract:
In this work, a fiber-coupled diode laser module emitting around 1116 nm with an output power P < 60 mW is realized. As a laser light source a distributed Bragg reflector (DBR) ridge waveguide diode laser is applied. The module comprises temperature stabilizing components, a micro-lens system as well as an optical micro-isolator. At the output, a polarization-maintaining single-mode fiber (PM-SMF) with a core diameter of 5.5 µm and a standard FC/APC connector are utilized. The generated diffraction limited beam is characterized by a narrow linewidth ( σν < 10 MHz) and a high polarization extinction ratio (PER > 25 dB).
