Temperature Control Module:
DTC 110
|
|
Plug-in Module for Diode Laser Supply and
Monitor Unit DC 110 |
|
|
|
|
The temperature control DTC 110 regulates the temperature of the laser diode to better than 1 mK and can also be used to fine-tune the laser wavelength (typical tuning sensitivity of commercial laser diodes: 0.1 - 0.3 nm / °C). The set value of the temperature is adjusted by a precision potentiometer. The standard temperature range of the DTC 110 is 0°C to 50°C (15-40°C for DL 100). Bipolar control (heating / cooling) allows fast and stable controlling, even at conditions close to room temperature. In case a user wishes to employ the DTC 110 in a more general control task, e.g. to balance the temperature of nonlinear crystals, a special version of the DTC 110 with an extended temperature range (-50°C ... 150°C) and/or setpoint velocity limiter is available from TOPTICA Photonics. |

Numerous protection circuits for the laser diode |
|
- operational control via LEDs at the Controller and DL 100 laser head
- presetable value for minimum and maximum temperature (temperature surveillance) as well as maximum output current by precision trimmers
- acoustic and optical indication (buzzer and LEDs, also error warning to the control system and / or a computer) when limits are reached
- double shielding of the case significantly reduces pick-up of ambient voltage transients, operation possible close to pulsed laser sources
- fast active protection mechanism prevent the surpassing of adjustable limits for the maximum heating current and temperature limits
|
|
|
|
- sub-D9-connectors for connection to TEC and temperature sensor
- BNC-connector for monitoring / surveying the active temperature control (1V / 1 °C)
- relevant output data to the Monitor Unit DC 110 are also available as analog signals: Tact, Tset, Tmin, Tmax, Imax, ITEC
- computer control optional via analogue interface DCB 110 possible
