Understanding 808nm Laser Chips for Medical and Industrial Applications

🧠 About This Product

808nm VCSEL (Vertical-Cavity Surface-Emitting Laser) emitter chips provide efficient near-infrared emission with model-dependent wavelength range, beam divergence, and electro-optical characteristics. This 808nm portfolio covers 11 power options from 5mW to 3W, supporting integration from compact sensing illumination to higher-power optical/thermal subsystems. Bare-die options are available, and we support SMD/COB packaging and project-based customization from R&D to mass production.

808nm is widely used across Nd-doped solid-state laser pumping (e.g., Nd:YAG / Nd:YVO₄), NIR sensing illumination, and certain thermal processing/industrial applications. These VCSEL chips provide a more symmetric circular beam profile (system-dependent) compared with typical edge-emitters and a more concentrated divergence than LEDs (model-dependent). For pumping architectures, narrow spectral width (model-dependent) and low wavelength temperature coefficient dλ/dT (typ. ~0.059–0.073 nm/°C, where specified) support system-level wavelength budgeting.

Key differentiators:

• Wide power range: 5mW → 3W (11 models)
• High PCE: up to ~46% (typ.) in low-power models; ~35–42% (typ.) in mid/high-power models
• Compact die sizes: ~140µm to ~1120µm (model-dependent)
• Symmetric circular beam: More symmetric beam profile simplifies optical design vs edge-emitters
• QCW and CW options: D-V0808M-2000-0042 is CW-specific
• Wavelength range: model-dependent (see datasheet)

Project-dependent screening/traceability & compliance documentation available upon request.
