Innovative Light Sources — Technological Breakthroughs

LightRun Light Sources Empower High-Precision Optical Applications

The LightRun Light Source Series is designed to meet the demanding requirements of high-precision optical applications, delivering outstanding performance in power output, spectral linewidth, and long-term stability. These sources have become core components in many industry-standard systems.

The series mainly includes two core product lines — lasers and ASE broadband light sources. With professional engineering design and flexible adaptability, they support a wide wavelength range and adjustable power levels, providing reliable and application-specific optical solutions for optical sensing, device testing, and laser system integration.

(I) LIGHTRUN Light Source Series — Core Categories

1. Lasers

LightRun laser products feature high-performance semiconductor laser chips, integrated with precision driving circuits and temperature control systems to ensure dual stability in both output power and spectral characteristics. This guarantees reliable long-term operation.

Applications: Serve as seed lasers for high-power laser systems or as stable sources for optical device production and performance testing.

Package Options: Available in benchtop and modular configurations to meet the needs of both laboratory R&D and system integration environments.

2. ASE Broadband Light Sources

As incoherent light sources, ASE broadband sources operate by pumping erbium-doped fibers with semiconductor lasers, producing amplified spontaneous emission. Through spectral broadening techniques, they achieve wideband spectral output.

Key Features: Wavelength coverage across the C+L bands, >3 dB spectral width, and single-mode transmission capability.

Output Options: Available with standard single-mode or polarization-maintaining fibers, offering flexible integration for diverse system requirements.

Applications: Especially suited for fiber sensing and other high-precision optical measurement scenarios.

In addition, the high-power broadband sources in the series combine wide spectral coverage with high output power, supporting multi-wavelength parallel applications in laboratories and production lines. This effectively overcomes the limitations of traditional light sources in wavelength coverage and output power.The femtosecond laser models, featuring ultrashort pulse durations and high peak power, play a crucial role in supercontinuum generation, time-resolved sensing, and other advanced research and precision measurement fields. With wide wavelength tunability and adjustable power, they provide reliable support for technological innovation and performance upgrades.

(II)  LIGHTRUN Light Source Series — Core Technologies

The excellence of the LightRun series stems from a foundation of core technological innovations that drive its superior performance and reliability.

1. High-Performance Chip Selection

At the heart of every LightRun source lies a high-stability semiconductor laser chip — the true “heart” of the device. These chips are rigorously screened and tested to maintain stable output over extended operation, minimizing performance fluctuations and ensuring consistent reliability in demanding environments.

2. Innovative Temperature Control Technology

Temperature variation significantly affects a light source’s output power and spectral linewidth, especially under extreme conditions. LightRun products employ innovative active temperature control technology that continuously monitors internal thermal changes and adjusts in real time to maintain optimal working conditions. Whether operating in high, low, or rapidly changing temperatures, LightRun sources deliver consistent high-precision performance and reliability.

3. Advanced Packaging Processes

In both laser and broadband light source designs, advanced packaging technology plays a vital role in combining high-quality chips with precision temperature control systems.

LightRun adopts a high-reliability architecture to ensure full lifecycle stability, offering multiple compact and integrable package formats (e.g., benchtop and modular designs). The optical-path and thermal-management co-design maintains long-term beam alignment stability and efficient heat dissipation, ensuring sustained optimal operation within end-user systems.

(III)  LIGHTRUN Light Source Series — Diverse Applications

With exceptional optical power and low-noise characteristics, the LightRun light sources (including broadband and fiber laser products) demonstrate strong competitiveness and commercial potential across key sectors such as optical communication, fiber sensing, industrial manufacturing, and scientific research.

1. Optical Communication — Enhancing Transmission Efficiency and Network Economics

In a backbone network upgrade project by a provincial branch of China Mobile, a 1550 nm single-mode laser (200 mW output) was deployed as the core signal source. Compared with conventional sources, this laser offers higher output power and superior SNR, extending unrepeated transmission distance, reducing the number of relay stations, and lowering total network deployment cost.

2. Fiber Sensing — Ensuring Structural Safety with Precision Monitoring

In a cross-province oil and gas pipeline project by the China Oil & Gas Pipeline Network Corporation, a high-power ASE broadband light source was integrated into a Distributed Acoustic Sensing (DAS) system. Installed along the same cable as the pipeline, the fiber enables 24/7 real-time monitoring across tens of kilometers.
With high-sensitivity vibration detection, it identifies third-party excavation or intrusion events with meter-level accuracy, forming a no-blind-zone intelligent protection system for critical infrastructure.

3. Industrial Inspection and Frontier Research — Driving Precision Manufacturing and Scientific Discovery

In a study conducted by a CAS (Chinese Academy of Sciences) institute, a femtosecond laser (50 fs pulse width) was used to investigate ultrafast chemical reaction dynamics. The system captured transient intermediate states in real time, and the resulting findings were published in Nature Communications.

As the demand for optical communication and precision measurement continues to rise, the LightRun Light Source Series will remain driven by innovation, focusing on overcoming key challenges in bandwidth, wavelength precision, and stability.

By continuously improving power stability, spectral purity, and introducing multi-mode modulation and intelligent temperature control features, LightRun aims to deliver next-generation products that fuel the high-quality development of the photonics industry.

Finally, LightRun Photonics sincerely welcomes collaboration with experts and partners across the optical communication and precision measurement sectors to explore new opportunities and advance the future of light source technology together.
