1 paź 2021 · This driver’s internal loop compensation is optimized for laser module assemblies such as 14-pin butterfly packages, provides a maximum output current of ±2.5 A, and temperature stability of ±0.002 °C.
5 sie 2024 · This short article provides basic information on laser diode drivers, and why they should be used to bias a laser diode instead of a standard DC supply. It provides a basic overview of how they work and the many types of drivers available.
Here, we present a compact, relatively inexpensive high-Vf laser driver with an integrated, high-precision temperature controller for lasers with an internal thermoelectric cooler (TEC), equipped with a microcontroller for direct control via a computer (Fig. 1).
insertion force (ZIF) socket accepts all standard 14-pin butterfly laser diode packages. Easy to use configuration cards allow the laser mount to be configured for all possible laser pin assignments. Designed primarily for Laser Diodes, the LM14S2 can also be used with many two port Electro-optic devices that are in 14-pin butterfly packages.
The tunable laser reference design board (demo board) demonstrates autopower control (APC), autotemperature control (ATC) and autofrequency control (AFC). Figure 3 shows simplified setup of the demo board. The demo board has a mount space for a tunable DFB laser module in a 14-lead butterfly package. The demo board also provides a power
The CLD1015 Laser Diode and Temperature Controller is a complete driver package designed to drive and cool pigtailed butterfly laser diodes (see the Pin Diagram tab for details). It contains a built-in mount for portability and mechanical stability.
Koheron CTL101 is a low noise current driver with modulation combined with a temperature controller. It is designed to drive narrow-linewidth laser diodes in butterfly package. The CTL101 fits in a 75 mm x 75 mm square, uses a single 5 V supply, and can operate between 0 and 50°C. The CTL101 is conduction-cooled.
