Laser performance of Cr4+:Y2SiO5

Abstract

Laser action in chromium-activated forsterite for near-infrared excitation: Is Cr 4+ the lasing ion?

Thermal properties of single-phase Y2SiO5

“…doped Y 2 SiO 5 crystals to be used as blue phosphor or Cr 4+ -doped Y 2 SiO 5 as a saturable-absorber Q-switch laser. [8][9][10] As an important phase in the SiO 2 -Y 2 O 3 -Si 3 N 4 phase diagram, 11,12 Y 2 SiO 5 is frequently identified as a precipitated phase at the grain boundaries of sintered Si 3 N 4 with Y 2 O 3 or Y 2 O 3 + SiO 2 as sintering aids. And it is confirmed that Y 2 SiO 5 can improve the high-temperature performance of silicon nitride.…”

Laser crystals and ceramics: recent advances

“…The CW laser output power is given in mW, W, kW. In understanding some date see also GeO 4 , and LiScGeO 4 crystals doped with chromium ions has also been the subject of detailed studies [268][269][270][271]. It is possible that lasing chromium has only a four-valence state in these compounds [270][271][272][273][274][275].…”
