R13D-675nm High Power Diode Laser Components

Product Overview

The R13D-675nm 15W High-Power Semiconductor Laser Module stands as a core component within RealLight's flagship AW multi-functional series, engineered specifically for OEM/ODM medical device manufacturers, photodynamic therapy (PDT) research, and industrial spectral analysis. Driven by high-efficiency single-wavelength 675nm chip technology, this module delivers up to 15W of continuous-wave (CW) output power. Featuring a narrow spectral width below 4nm and a low temperature drift coefficient of just 0.3 nm/°C, it provides exceptional beam uniformity and long-term operational stability.

To meet the stringent optical delivery and precision standards of medical aesthetic system integrators, the module incorporates a standard SMA905 detachable fiber interface paired with a 200μm core diameter / 0.22 NA fiber—ensuring a flat-top energy profile across the delivery beam. Additionally, a built-in 520nm green aiming beam (5mW) provides high-contrast visual alignment to simplify aiming and targeting during operation.

To safeguard system performance during sustained high-power operation, the module features a comprehensive safety monitoring setup. Integrated photodiode (PD) sensors and an NTC thermistor (10kΩ @ 25°C) deliver real-time feedback on optical power and heat sink temperatures. A fiber sensor (FS) detection pin actively mitigates laser leakage risks caused by loose fiber connections, while a field-replaceable protective window protects internal optics from ambient contamination—significantly extending module lifespan and streamlining routine field maintenance. Capitalizing on the targeted optical absorption properties of the 675nm band, this module serves as a robust, highly customizable engine for next-generation platforms focused on collagen remodeling, deep photobiomodulation (PBM), and photosensitizer activation.
