The SDC-4U diode driver is an advanced solution designed for the precise and efficient operation of high-power Nd:YAG-like solid-state lasers. This family of laser diode drivers integrates a robust current source, a capacitor bank, and a capacitor charger, making it a comprehensive choice for laser pumping applications. Its capability to power and control a Pockels cell driver for generating Q-switched pulses further enhances its versatility. The SDC-4U also offers the ability to send output synchronization signals to other equipment, either in sync with or shifted relative to the TTL pulse applied to the Pockels cell driver.

Designed with flexibility in mind, the SDC-4U diode driver accommodates a wide range of input voltages from 110-240VAC, ensuring compatibility with various power sources. Its high compliance voltage, which can reach up to 500V depending on the model, and a maximum output current of up to 400A, make it suitable for demanding applications. The driver supports high average power outputs of up to 1500W, with pulse widths typical for Nd:YAG pumping ranging from 50 to 300 microseconds. Fast rise and fall times, along with pulse repetition rates of up to 50Hz, ensure efficient and reliable performance.

The SDC-4U is engineered for both internal and external synchronization modes, providing seamless integration with external Pockels cell drivers. Customization options, including multiple outputs, are available to meet specific application requirements. Safety and protection features are integral to the design, safeguarding against overcurrent, overheating, incorrect buffer voltage, and excessive synchronization pulse frequencies. The unit is equipped with a door-interlock connection and quick discharge resistors to enhance operational safety.

For ease of use, the SDC-4U features a user-friendly interface with a 10-inch touchscreen display, complemented by RS-232 and RS-485 machine interfaces for versatile connectivity. Forced-air cooling with built-in fans ensures optimal thermal management, maintaining performance within the operating temperature range of +10 to +40 °C. The SDC-4U diode driver is a reliable and adaptable choice for high-power laser applications, offering precision, safety, and customization to meet diverse operational needs.
