• Cutting highly reflective metals can intermittently cause laser light to be reflected back at the laser, causing failures in the beam delivery, particularly in the hundreds of fiber splices found inside a fiber laser.
     

  • Damage to fiber or disk lasers due to back-flash will result in costly repairs which will also take the laser out of service. 
     

  • Fiber lasers occupy a very narrow range of wavelength around 1 micron which does not absorb well into Aluminum or "red metals" (copper, bronze, brass)

Back Reflection Immunity

Back Reflection or Back-flash 
Direct-Diode Advantages
  • TeraDiode lasers generate the beam in free space then focus and launch into a single delivery fiber, completely eliminating fiber splices from the resonator. Thus TDI lasers are totally immune to back reflection issues. 
     

  • TeraDiode lasers are more productive & efficient than fiber or disk lasers when processing any reflective materials.
     

  • TeraDiode laser light has a shorter wavelength which is better absorbed by reflective metals.  
     

  • DDL weld reflective materials with superior results compared to fiber
     

  • Our laser light has 30% greater absorption in Aluminium compared to a fiber laser at 1060nm
