01 / Product introduction

Product introduction

This 2330 nm DFB (distributed feedback) semiconductor laser is built on advanced antimonide (GaSb) compound-semiconductor epitaxy with single-longitudinal-mode grating feedback. Its centre wavelength matches the near-infrared absorption band of the carbon monoxide (CO) molecule, and it offers high spectral purity, very narrow linewidth and excellent current and temperature tuning — an ideal source for high-precision TDLAS gas detection systems.

Core application scenarios

01
Industrial process and combustion monitoringReal-time CO concentration monitoring in steelmaking, petrochemical furnaces, power-plant flue gas and combustion-efficiency optimisation.
02
Mining and fire safetyEarly fire warning through underground coal-mine CO detection, and toxic-gas monitoring in tunnels and confined spaces.
03
Environmental monitoring and researchAtmospheric pollution analysis, high-precision greenhouse and trace gas detection, and spectroscopic metrology.

Core advantages

01
Precise wavelength matchEmission across 2325–2333 nm sits in the strong carbon-monoxide absorption region, free from cross-interference by water vapour, CO₂ and other background gases.
02
Single-mode spectral puritySingle-longitudinal-mode output with low relative intensity noise supports trace-level detection sensitivity.
03
In-house antimonide IDM platformA self-controlled GaSb full-chain manufacturing platform underpins mid-infrared capability with excellent product stability and consistency.
04
Mode-hop-free continuous tuningWide-range wavelength tuning without mode hopping via current and temperature, with fast response and a threshold current below 60 mA.
