976nm High-efficiency Pumping Technology

GW Laser has mastered the core technology of 976nm pumping, and has led the industrialization of bidirectional 976nm pumping technology in China through its own continuous technological breakthroughs and industrial chain cooperation.
  • Domestic pioneer

    GW took the lead in realizing the large-scale mass production and manufacturing of 976nm pump technology GW is the first company in China to realize the mass industrialization of 976nm products
  • Ultra-high electrical-optical conversion efficiency

    GW’s 976nm pump technology enables laser products with electro-optical efficiency up to 42%, while the laser from other laser manufacturers’using 915nm pumping technology only offers EO efficiency of 25~32 %
  • Ultimate energy density

    SC-SM 3KW achieves 20um optical cable output, M2 is less than 1.3, and energy density reaches 2.4 million W/mm2, which is currently the physical limit of industrial fiber lasers
  • Energy saving and cost reduction

    The 10,000-watt high-power product is the mainstream application of laser cutting for medium and thick plates. The annual power saving brought by one laser is more than $1,500, which greatly saving cost

976nm High-efficiency Pumping Technology

976nm solution can solve the problem of 915nm solution the nonlinear optical effect.The active fiber for pump light in the 976nm brand is 2-3 times that of the pump light in the 915nm band.Shorter gain fiber,lower non-linear optical effect,which need less material costs
  • 976nm pump technology

    Optical to optical conversion efficiency>80%/ ectrical to optical conversion efficiency>42%
    Higher pump absorption efficiency/ Shorter gain fiber fiber length /Weaker non-linear effect
    Lower total power requirement of the pump source
  • 976nm pump technology

    Optical to optical conversion efficiency>70% /Electrical to optical conversion efficiency>30%
    Lower pump absorption efficiency/Longer gain fiber fiber length/Stronger non-linear effect
    Higher total power requirement of the pump source

AAC Active Air Cooling Technology

Build upon the mature air-condition technology, the AAC technology removes the water and utilize the refrigerant as the coolant to cool the laser directly. The AAC technology not only eliminate the winter freezing and summer water-condensing problem associated with water coolant, but also improve the overall electrical efficiency by ~30% but also reduce the overall size and weight by 30~40%

Comparison of different heat dissipation methods

  • Passive air cooling solution - case temperature
  • Active Air Conditioning Direct Cooling Solution-Bulk Temperature
  • Passive air cooling solution - laser chip temperature
  • Active air conditioning direct cooling solution - laser chip temperature

The temperature change of the device after the two heat dissipation schemes emit light at full power for 10 minutes at different temperatures

SPP Super Piercing Pulsing Technology

Build upon the mature air-condition technology, the AAC technology removes the water and utilize the refrigerant as the coolant to cool the laser directly. The AAC technology not only eliminate the winter freezing and summer water-condensing problem associated with water coolant, but also improve the overall electrical efficiency by ~30% but also reduce the overall size and weight by 30~40%
