AWS-A Series Single Mode Diode Laser System

RealLight RealStable® AWS-A Benchtop Single-Mode Diode Laser System Product Introduction
1. Product Overview
The AWS-A series is an integrated benchtop single-mode fiber laser system independently developed by RealLight. Different from miniature bare laser modules, it is a complete factory-calibrated all-in-one unit integrating laser driver, closed-loop TEC thermostatic cooling, power supply, main control board and safety interlock. Equipped with dedicated upper computer monitoring software, it supports real-time equipment status reading and online firmware upgrade. A physical emergency stop switch is built in for safety protection. Standard available visible wavelengths cover 405 / 450 / 520 / 638 / 650 nm, delivering high-quality single-mode Gaussian beam. It is widely adopted for high-precision fluorescence detection, microscopic imaging, material scientific research and miniature precision laser processing. Plug-and-play design eliminates extra power and control circuit construction, serving as standardized desktop excitation light source for university labs and analytical instrument manufacturers.

2. Core Product Advantages
2.1. Built-in closed-loop TEC cooling for long-term power stability
Independent thermoelectric cooling loop is integrated inside the unit. Peak-to-peak power fluctuation is better than ±2% over 4-hour continuous operation. Spectral linewidth is below 3 nm with wavelength tolerance within ±10 nm, delivering outstanding monochromaticity. No energy drift occurs during long data acquisition, ensuring repeatable results for quantitative fluorescence and trace sample testing without frequent calibration.

2.2. Standard single-mode Gaussian beam for high micro-detection resolution
4/6/9 μm single-mode fiber with NA=0.22 outputs ideal Gaussian energy distribution. The tiny focused spot enables micron-level pinpoint excitation for confocal microscopy, single-cell fluorescence and trace material characterization. It suppresses spectral stray peaks and significantly improves signal-to-noise ratio. Dual fiber connectors SMA905 and FC/PC are optional.

2.3. All-in-one benchtop unit with PC software & emergency stop
Integrated power supply runs on +12 VDC input. Matching host software monitors real-time temperature, power and runtime, supporting lossless online firmware upgrade. A hardware emergency stop button instantly cuts laser output in abnormal conditions, fully complying with safety standards for scientific instruments.

2.4. Analog + USB dual control for automated integration
0~5 V analog modulation input paired with USB digital communication. Output power is steplessly adjustable from 0 to 100%. Synchronous linkage with timing generators, automated experimental platforms and microscopes is supported to facilitate secondary software development for high-throughput testing.

2.5. Low-power compact chassis with wide environmental tolerance
Typical power consumption below 7 W, dimension 180×102×180.2 mm and total weight 1.2 kg for stable desktop placement. Operating temperature ranges 10~35 ℃; storage -10~60 ℃ with RH 0~70% RH. Stable long-term performance is maintained in constant-temperature labs and regular research workshops.

2.6. Comprehensive customization service
Custom higher power grades for each wavelength are available. One-stop development of fiber optical paths, imaging lenses, therapeutic handpieces and exclusive control programs is provided for customized research equipment.

3. Main Application Fields
3.1. Scientific Fluorescence Spectroscopy
405 / 450 / 520 blue-green single-mode lasers act as excitation sources for trace organics, biomacromolecules and environmental pollutants. Narrow spectrum and stable power enhance detection accuracy of trace substances.

3.2. Confocal Microscopic Imaging
Fine single-mode Gaussian beam realizes pinpoint fluorescence excitation on cell slices and tissue micro-regions. Micron-scale focused spot greatly boosts spatial resolution of microscopic observation.

3.3. Flow Cytometry
Multi-wavelength combinations deliver steady single-mode light to excite cellular fluorescent markers and guarantee precise quantitative cell analysis.

3.4. Advanced Material Research & Micro Machining
Applied for thin-film optical characterization, photocatalysis experiments and miniature micro-welding of microelectronics. Precise low-energy single-mode beam prevents thermal damage to substrates.

4. Product Summary
The AWS-A benchtop single-mode diode laser system is a complete all-in-one scientific light source with core strengths: self-contained design without external power supply, fine single-mode Gaussian beam, power fluctuation less than ±2% within 4 hours, built-in TEC temperature control, PC firmware upgrade + emergency stop, dual analog & USB control. Covering all mainstream visible wavelengths from 405 to 650 nm, it is plug-and-play, ideal for desktop high-precision spectral analysis and automated research equipment integration. Customization on power grades, optical paths and control software is fully supported, making it a preferred domestic single-mode excitation light source for universities and analytical instrument manufacturers.
