Kilowatt-Level Fiber Lasers for Combustion Research

Combustion diagnostics requires high-energy, narrow-linewidth, and highly stable light sources. Techwin’s kilowatt-class fiber lasers are engineered to support advanced measurement techniques—delivering continuous high power, stable beam quality and resilient performance in harsh experimental environments.

Why Kilowatt-Level Fiber Lasers Matter in Combustion Diagnostics

• High optical power for long-range propagation and penetration through particulate-laden flame zones
• Narrow spectral linewidth for selective species excitation and precise spectroscopy
• Stable beam quality (M² optimized) for uniform illumination in PIV and imaging
• Robust continuous operation for long test campaigns
• Fiber-based architecture for enhanced thermal management and reliability

Common Diagnostic Techniques Supported

These lasers enable multiple advanced diagnostics including Laser-Induced Fluorescence (LIF) for species mapping, Particle Image Velocimetry (PIV) for flow-field analysis, Coherent Anti-Stokes Raman Spectroscopy (CARS) for temperature and composition, absorption-based pollutant monitoring, and high-speed imaging of transient flame phenomena.

Key Features & Performance Highlights
