Features- Designed for Thorlabs' Half Butterfly Gain Chips with Labels to Ensure Proper Wiring
- Excellent for Home-Made External Cavity Lasers
- Offers DB9 Connections for Thorlabs' LD and TEC Controllers
The TLK-C03 interfaces a half butterfly gain chip to Thorlabs' laser diode drivers and TEC controllers. This easy-to-use device has numbered sockets for error-free connection to Thorlabs' half butterfly gain chips. Common applications are testing a half butterfly gain chip before integration into a complete system, or in an external cavity laser (see the photo at top right). Thorlabs' TEC controllers mate to the unit's male DB9 connector, while LD drivers attach to the female DB9 connector. Third-party controllers may also be used if wired to mate with the TLK-C03's DB9 pin configurations below. The half butterfly connection cable (included) can be detached from the TLK-C03's male DB15 connector (below) if a different wiring harness is needed. Laser Diode Driver
