Twin DFB Diode Laser


Product Introduction

Twin DFB Diode Laser

The driver unit is included in the iScan control unit. It comprises two CCTC modules. Each module controls both laser current and temperature of one laser diode. The laser frequency tuning is accomplished by changing either the current (for fast but small steps) or the temperature (for large scans). The sontrol unit is ready for remote control via RS-232 or USB.



- Arbitrarily tunable beat note frequency

- Large tuning range up to 2 THz

- FiberLock stabilized single-mode fiber coupling

- Optimized for cw THz generation

- Including drivers HV or RF, resp. optional
