14BTF Diode Laser Components

RealLight Model 14BTF Diode Laser Module Product Introduction

1. Product Overview
Model 14BTF belongs to RealLight self-developed AW series single-emitter fiber-coupled diode laser modules. Adopting integrated TEC temperature-controlled packaging, it provides two output configurations: single-mode and multi-mode, covering mainstream visible wavelengths from 405 nm to 650 nm. Compact in size, the module delivers stable output power, uniform beam profile and outstanding long-term reliability, with abundant wavelength options. It serves as a standardized light source component for solid-state laser pumping, fluorescence spectroscopy detection, precision micro-processing, laboratory optical research and other applications, ideal for mini optical analyzers and desktop research platforms.

2. Core Product Advantages
2.1 Single-Emitter Fiber Coupling with Controllable Beam Quality
Precision coupling design for single laser chip offers two fiber delivery options: single-mode delivers pure beam with small divergence for high-precision spectroscopy and microscopic excitation; multi-mode provides higher average power and uniform spot for pumping and large-area fluorescence excitation. Standard FC/PC and SMA905 fiber connectors are compatible with most optical instruments.

2.2 Full Visible Wavelength Portfolio for Flexible Selection
Five standard visible wavelengths (405 nm, 450 nm, 520 nm, 638 nm, 650 nm) cover violet-blue, green and red bands to match diverse optical demands including fluorescence excitation, crystal pumping, visual alignment and material photo-modification. Custom fiber lengths are available on request.

2.3 Built-in TEC Thermostat for Long-Term Power Stability
Integrated thermoelectric cooler (TEC) and 10 kΩ thermistor enable precise real-time temperature monitoring. Spectral linewidth FWHM < 3 nm with wavelength tolerance within ±10 nm, ensuring minimal power drift during continuous operation for repeatable experimental and processing results.

2.4 Miniature Integrated Package for Easy Integration
Optical, cooling and temperature sensing components are highly integrated into a compact unit. Standard fiber length reaches 100 cm with customization supported. Standardized electrical parameters simplify embedding into portable detectors, desktop spectrometers and compact laser processors to cut R&D integration cost.

2.5 Industrial-Grade Hermetic Packaging for High Durability
Mature optical coupling and sealed housing block dust and moisture. Sufficient TEC operating margin (max 2.2 A current, max 8.7 V voltage) guarantees stable long-term operation in labs and manufacturing workshops with low maintenance overhead.

3. Main Application Fields
3.1 Pumping Source for Solid-State Lasers
405 / 638 / 650 nm variants act as auxiliary pump sources for microchip lasers, compact Q-switched lasers and nonlinear optical experiments. Single-mode beam enables precise coupling into gain crystals for stabilized laser output.

3.2 Fluorescence Detection & Analytical Instruments
405 nm UV, 450/520 nm green wavelengths excite biological fluorescence, chemiluminescence and photoluminescence of materials, paired with spectrometers and microscopic imaging systems widely used in environmental testing, biological labs and material characterization.

3.3 Compact Precision Laser Processing
High-power multi-mode versions for resin curing, surface photo-modification, fine marking and PCB micro-machining; uniform spot ensures consistent processing quality.

3.4 Optical Research for Universities & Labs
Multi-wavelength standardized miniature light sources support Raman pre-excitation, nonlinear optics, optical sensing and educational optical bench construction. Small footprint facilitates multi-optical-path setup assembly.

4. Product Summary
Model 14BTF is a standardized fiber-coupled diode laser module under RealLight AW series. Combining single-emitter precision coupling, built-in TEC temperature control, multiple wavelength options and dual single/multi-mode configurations, it balances beam quality and output power. The compact integrated design lowers equipment integration barriers and covers pumping, fluorescence detection, precision machining and optical research scenarios. With standardized parameters and broad compatibility, it serves as a cost-effective domestic miniature visible fiber laser module for analytical instrument manufacturers, research institutes and compact laser equipment OEM mass matching.
