A DBR is a Bragg mirror, i., a light -reflecting device (a mirror) based on Bragg reflection at a periodic structure. A distributed Bragg reflector laser is a laser, where the laser resonator is made with at least one semiconductor-based distributed Bragg reflector (DBR) outside the gain medium (the active region). It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide. The D2-200 laser module is a complete redesign of our robust Distributed Bragg Reflector (DBR) diode laser. The D2-200 houses a new Virtual Point Source (VPS) DBR laser. The VPS design uses a proprietary lensing system to reduce astigmatism, matching the divergence in the fast axis to that of the. These qualities make DBR lasers ideal for applications where precision is paramount – such as telecommunications, spectroscopy, and sensing. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The optical gain is provided by double. Optoprim, with its partner Photodigm, offers a choice of high performance single frequency DBR laser modules from 730 to 1090 nm, with a choice of nearly 30 wavelengths. Photodigm control all aspects of design and production.
