850nm 5mW Benchtop Polarization-Maintaining SLD Light Source

Idealphotonics' Ultra-Width Series 850nm High-Stability Single-Mode Pump Light Source utilizes a TEC wavelength-stabilized single-mode semiconductor laser, offering wavelength stability and high output power. Based on an advanced microprocessor control system, combined with high-precision ATC and ACC (APC) control circuits, this light source achieves highly stable laser output while ensuring quick and intuitive operation. We can also provide corresponding communication interfaces and control software based on user requirements for computer control. This light source features a Turn-Key pump laser protection function to effectively prevent damage due to user error. Power can be coarsely adjusted (in 1mW steps) or finely tuned (in 0.1mW steps). 850nm single-mode pump light source is a highly integrated benchtop system light source, equipped with a high-definition LCD display, continuously adjustable output power, and synchronous display of current and voltage, making it ideal for experimental scientific research and production testing. Additionally, the company can provide modular packaging tailored to user needs for easy system integration.
