Suggestions:
- For DPSS lasers, please select the numbers of diode driving and TEC cooling according to the used numbers in the lasers.
- For high-power 1064nm DPSS lasers, no need to use TEC controls since there is water cooling in the laser system. The diode laser and laser crystal will be cooled via heat conduction of the base which is water-cooled. For 532nm DPSS lasers, only TEMP3 is needed. For 355nm DPSS lasers, TEMP3 and TEMP4 are needed.
- Default outputs are 1set diode laser driver. Others are options.
- In general, water cooling is better than air cooling for DPSS lasers. If there is no water cooling in the system, TEM2 is often used to cool the laser crystal.
2. LDD Series Laser Diode Drivers without TEC
The laser diode driver ST-LDD-AAVV is a high current-constant laser diode driver without thermo-electric cooler controller. Current control, transient suppression, over-temperature protection, short circuit protection, and over current limit are provided. 2 digital meters show the output current and output voltage. The driver is mainly used to drive diode modules.
Specifications:
- Model: ST-LDD-AAVV
- ST-LDD- ST series laser diode drivers
- AA-maximum output current (A). The output current is continuously adjustable.
- VV-maximum output voltage (V). The output voltage is determined by current & diode’s resistance.
- Input voltage: 220VAC, +/-15%
- Voltage noise: <0.1% p-p
- Current noise: < =50mA
- Un-stability: <0.1%
- Dimension: 482×88x260mm
- Net weight: 6.5kg
Remark:
To select a driver, you may finalise the output voltage first and then finalise maximum output power. The maximum output current will be the maximum power divided by the output voltage.

3. ST-LDDJ Series Diode Drivers
ST-LDDJ series diode drivers are all-in-one systems which consists of system controller, diode driver and TEC controller. The diode drivers have two types of outlooks: OEM 19” drivers and bench- top drivers. The users may integrate our drivers into their systems or just individually use in the laboratory. Our drivers can drive one laser diode and one TEC cooler.
Features:
- OEM 19” drivers are 2U size and the input is 220VAC 50Hz
- Support one diode and one TEC cooler
- Output current continuously adj., and voltage self adaptive
- RS232 port to communicate with a PC with our software STXFMate
- INTERLOCK and temperature protection
- Output current can be controlled internlly or externlly
- Optional PWM modulation output
