DM-8E5A-8OD 808nm Pump Laser Diode

For engineers sourcing stable pump light sources for solid-state lasers, medical aesthetic devices and industrial processing, poorly made laser diodes often cause short service life and unstable beam output.
Today we recommend a fully validated industrial model: DM-8E5A-8OD (HGLD-808-COS-D-5W) from HAUCORE, a mature 5W 808nm COS packaged laser diode with mass production verification.

1. Core Unique Advantages of DM-8E5A-8OD

This laser diode stands out from ordinary low-power pump diodes with 4 core strengths:

DM-8E5A-80D

1. AuSn gold-tin soldering process
   Low thermal resistance, excellent heat dissipation, effectively reduce chip aging speed and extend service life.
2. High electro-optic efficiency up to 58%
   Typical slope efficiency reaches 1.3 W/A, low working voltage (<1.9V), lower power consumption for your whole device.
3. Compact COS chip-on-submount packaging
   4.5×4.5mm ultra-small size, easy to integrate into miniaturized laser modules; clear positive/negative pin layout for simple circuit assembly.
4. Stable narrow spectrum
   Spectral width less than 2nm, wavelength drift only 0.3nm/℃, consistent pumping performance in standard working temperature (15~30℃).

2. Key Technical Parameters (25℃ QCW)

• Rated output power: 5W
• Central wavelength: 805nm (800–810nm tolerance)
• Threshold current: ≤0.7A, operating current: 5A
• Fast axis divergence <50°, slow axis divergence <8°
• Storage temperature range: -40℃ ~75℃

3. Main Application Scenarios for DM-8E5A-8OD

This market-tested laser diode fits four major industries perfectly:

1. Solid-state laser pump source
   Ideal for Nd:YAG/Nd:YVO4 crystal pumping to generate 1064nm infrared and 532nm green lasers.
2. Industrial laser processing
   Small laser marking, micro cutting and precision engraving equipment.
3. Medical & beauty equipment
   808nm hair removal, skin rejuvenation and physical therapy devices.
4. Laser display & scientific research
   Laboratory optical testing, miniature laser projection systems.

4. Why Choose HAUCORE DM-8E5A-8OD Over Generic Diodes

HAUCORE owns full vertical production chains from epitaxial wafer growth to packaging, all DM-8E5A-8OD units pass strict aging testing before delivery.
Unlike cheap unbranded laser diodes with unstable power output, this model maintains consistent optical performance for long-term continuous operation, cutting your after-sales failure rate for mass-produced equipment.

Conclusion
