SYS DC 110
Well-established analog driving electronics for tunable diode lasers
• Supply rack with linearly regulated, low noise power supply • Low noise and drift current, temperature and piezo drivers
• Supports numerous modules for laser stabilization • Modular setup for driving and locking various laser systems
• All important controls directly accessible on front of modules
The diode laser supply rack DC 110 serves as a general basis for all plug-in modules of the SYS DC 110 series. It provides the necessary supply and HV voltages as well as communication lines via an integrated backplane. The monitor unit DC 110/Mon of the Diode Laser Controller displays the most relevant laser parameters at a glance for up to three laser systems.
The DCC 110 modules are low-noise, analog current control modules. Four different models deliver currents up to 100 mA, 500 mA, 3000 mA and 5000 mA. The DTC 110 is a low-noise temperature control module that regulates the laser diode temperature with a precision of approx. 1 mK. Special versions are available for DFB diodes and for regulating the temperature of nonlinear crystals. The SC 110 is optimized for driving ECDLs, DFBs or scanning Fabry-Perot interferometers. It can be configured in HV (150 V) or LV (24 V) mode. The “feed forward” feature controls the diode current during a Piezo scan to maximize the mode hop free tuning range of an ECDL system. The computer analog interface DCB 110 allows direct access to the backplane of the supply rack DC 110 for controlling the installed modules.
