AWMO-A Series Multi-mode Diode Laser Module

RealLight RealStable® AWMO-A Series Single-Wavelength Multi-Mode Diode Laser Module Product Introduction
1. Product Overview
The AWMO-A series is a standardized single-wavelength fiber-coupled multi-mode diode laser module independently developed by RealLight under the AW general laser product line, designed for lightweight supporting of various spectroscopic analytical instruments. Integrated with laser drive circuit and closed-loop TEC thermostatic cooling unit, the module delivers stable optical performance, ultra-low power consumption and ultra-compact size. It is equipped with dual standard control interfaces: PH2.0 hardware port and USB communication port, while fiber outlets support universal FC/PC and SMA905 connectors. Five mainstream visible wavelengths (405/450/520/638/650 nm) are provided as standard options, ideal for fluorescence spectrometers, flow cytometers, confocal microscopes, laser particle size analyzers and other precision analytical equipment. Custom higher power versions, secondary development and customized optical path design are available, making it a preferred built-in excitation light source for laboratory and industrial miniature optical instruments.

2. Core Product Advantages
2.1. Narrow spectrum & stable power for repeatable test data
Spectral linewidth below 3 nm and wavelength tolerance within ±10 nm deliver superior monochromaticity to reduce stray peaks on spectral baselines. The built-in closed-loop TEC temperature controller ensures peak-to-peak power fluctuation less than ±2% over 4 hours of continuous operation. Minimal energy drift eliminates frequent calibration, meeting strict standards for quantitative fluorescence and particle detection.

2.2. Miniature low-power integrated design for portable instruments
Compact dimension only 76.2×63.5×28 mm with weight under 150 g, occupying minimal internal equipment space. Typical power consumption is below 5 W, running on low-voltage 5 VDC / 2 A power supply. No bulky heat dissipation structure is required; a simple radiator enables stable operation, perfectly suitable for handheld and desktop miniature analytical devices.

2.3. 105 μm large-core multi-mode fiber for sufficient irradiation area
Uniform 105 μm / NA 0.22 multi-mode delivery fiber provides adequate luminous flux for batch samples and large-area biological specimen fluorescence excitation. Pluggable fiber design with dual FC/PC & SMA905 connectors is directly compatible with mainstream spectral detectors and microscopic optical components on the market.

2.4. Dual interface programmable control for automated testing equipment
PH2.0 10Pin hardware interface and USB digital communication are simultaneously supported. The upper computer software enables stepless power adjustment from 0 to 100%, allowing synchronous triggering with timing control systems and automated production lines to facilitate OEM secondary software development.

2.5. Stable performance under wide temperature & humidity
Operating temperature ranges from 10 to 35 ℃ (heat sink required); storage temperature -10~60 ℃ with relative humidity 0~70% RH. Consistent laser output is maintained in constant-temperature labs and regular industrial workshops without performance degradation caused by mild ambient fluctuations.

2.6. Comprehensive customization support
Custom higher output power for each wavelength is available. We also provide customized drive software, upper computer programs, fiber optical paths and therapeutic handpieces to realize one-stop matching for complete instrument systems.

3. Main Application Fields
3.1. Laser-Induced Fluorescence Spectrometers
Blue/green lasers at 405/450/520 nm act as excitation sources for detection of organic macromolecules and environmental pollutants. Narrow linewidth and stable power greatly improve fluorescence signal-to-noise ratio.

3.2. Flow Cytometers
Multi-wavelength modules are combined to excite fluorescent labels on cells; consistent power guarantees accurate quantitative measurement of cellular fluorescence signals.

3.3. Confocal Microscopes
Visible laser beams serve as excitation light for microscopic scanning of cell slices and tissue samples, with uniform multi-mode spots ideal for biological imaging.

3.4. Laser Particle Size Analyzers
638/650 red light sources adopt light scattering principle for particle size measurement. Long-term power stability ensures precise particle size data output.

4. Product Summary
