QC750-Touch™ QC Laser Driver

A new generation of QCL driver integrates a newly designed touchscreen UI, which greatly facilitates user operations and measurement. The circuit features extremely low current noise and temperature drift. The driver includes a TEC temperature controller and low noise current driver. It supports external analog signal modulation and displays real-time working status on the touchscreen. Our specially designed maximum current soft clamping can avoid damage to the laser chip caused by a large current. The driver also has a variety of protection mechanisms to maximize the security of the laser chip. The product is stable, reliable, and suitable for various QCL systems in university laboratories or R&D development.
