Optical Properties of LGDs

  • Refractive Index: With a refractive index of 2.4, LGDs can manipulate light in ways that glass and crystals cannot. This enables tighter focusing and reflection of beams.
  • Thermal Conductivity: As the most thermally conductive material on Earth, LGDs can dissipate heat that builds up in high-power laser systems. This helps lasers maintain stability and prevents damage.
  • Durability: Ranking 10 on the Mohs scale, LGDs are incredibly hard and resistant to scratching. This durability is vital for optical components facing high-energy beams.
