D2-200 DBR Laser Module
The D2-200 laser module is a complete redesign of our D2-100 Distributed Bragg Reflector (DBR) diode laser.
The D2-200 laser module is a complete redesign of our D2-100 Distributed Bragg Reflector (DBR) diode laser. The D2-200 can employ the new VPS (Virtual Point Source) DBR laser design from Photodigm – the premier manufacturer of DBR lasers for scientific applications. The VPS design uses a proprietary lensing system to reduce astigmatism and the divergence in the fast axis of the diode. The output is near Gaussian with a very low M2.
The D2-200 has also undergone a DFM process (Design For Manufacturability) to reduce drift in alignment making for a more reliable design than its highly popular predecessor.
The D2-200 employs two stages of temperature control and incorporates optical isolation for dependable long-term, mode hop-free operation.
DBR laser diodes are fabricated with the feedback grating patterned directly adjacent to the gain region of the diode. By virtue of this short cavity design, they are highly immune to vibrations and acoustic perturbations. The short cavity allows mode hop-free current tuning over more than 40 GHz. The tuning is very fast and is amenable to high-bandwidth servo control for easy locking to atomic and molecular transitions or offset locking to a reference laser.
