AWSO-A Series Single-Mode Diode Laser Module

RealLight RealStable® AWSO-A Series Single-Mode Diode Laser Module Product Introduction
1. Product Overview
The AWSO-A series is a compact single-mode fiber-coupled diode laser module independently developed by RealLight, designed for high-precision micro-spectroscopy and bio-optical analytical instruments. Integrated with an all-in-one laser driver and closed-loop TEC thermostatic control circuit, it delivers superior beam quality and long-term power stability. The miniaturized low-power unit is equipped with PH2.0 hardware port and USB dual control interfaces, while fiber outlets support universal FC/PC and SMA905 connectors. Five standard visible wavelengths (405/450/520/638/650 nm) are available. Its single-mode Gaussian beam fits high-precision testing equipment such as confocal microscopes, flow cytometers and laser particle analyzers. Custom higher power grades, upper computer programs and optical path designs are supported, making it the preferred built-in excitation source for scientific research and miniature precision analytical instruments.

2. Core Product Advantages
2.1. Premium single-mode Gaussian beam for high resolution micro-detection
Precision single-mode coupling with optional 4/6/9 μm fiber (NA=0.22) generates standard Gaussian beam with excellent coherence and tiny focused spot, enabling micron-level pinpoint excitation for micro-regions, single cells and trace samples. It greatly improves spatial resolution of optical instruments. The spectral linewidth is less than 3 nm for low stray baseline noise and high signal-to-noise ratio.

2.2. Closed-loop TEC temperature control with power fluctuation <±2% over 4 hours
Built-in thermoelectric cooling circuit ensures peak-to-peak power stability better than ±2% during 4-hour continuous operation, with wavelength tolerance limited within ±10 nm. No frequent calibration is required for long-term experiments, delivering repeatable data for quantitative fluorescence and trace substance measurement.

2.3. Miniature low-power design for easy equipment integration
Compact dimension of only 76.2×63.5×28 mm with weight below 150 g. Typical power consumption is under 5 W with 5 VDC / 2 A low-voltage input, eliminating bulky heat sinks. It can be easily installed inside desktop and portable devices to cut mechanical design costs.

2.4. Dual control interfaces for secondary development of automated equipment
Dual control modes: PH2.0 10Pin hardware port + USB digital communication. Output power is continuously adjustable from 0 to 100%. Linkage with upper computers and timing generators is supported to build automated high-throughput testing platforms, facilitating customized control program development.

2.5. Standard fiber connectors with wide compatibility
Dual FC/PC and SMA905 fiber connectors are provided for direct connection to most commercial spectrometers and microscopic optical paths without extra adapters, shortening assembly and debugging cycles.

2.6. Stable performance under wide temperature & humidity
Operating temperature ranges 10~35 ℃ (heat sink required); storage temperature -10~60 ℃, relative humidity 0~70% RH. No degradation of optical power or beam quality occurs after long-term operation in constant-temperature labs and standard industrial environments. Custom power grades and fiber specifications are available upon request.

3. Main Application Fields
3.1. Confocal Microscopes
