Luminescence from chromium–neodymium-doped lithium niobate

Studies of the EPR g factors and the local structure for the trigonal Nd3+ center in LiNbO3:Nd3+ crystal

“…Particularly, Nd 3+ -doped LiNbO 3 has been widely investigated because of applications in compact diode-pumped self-frequency doubled lasers [7][8][9][10]. Obviously, the properties of laser for this material are closely related to local structure and electronic behaviours of the impurity Nd 3+ .…”

Photoionization energies of Cr3+-doped LiNbO3

“…They are used in a variety of fields from fundamental research to industrial applications due to their ease of use, high light yields, durability, and long-term stability. Cr 3+ -doped LiNbO 3 has been proposed as a tunable laser system owing to its broad luminescence in the near infrared, high quantum efficiencies and its inherent nonlinear properties, with the corresponding potential for self-frequency doubling of the near-infrared luminescence to visible luminescence [1][2][3][4][5]. The emission in the near infrared spectral region alone makes this material potentially competitive with the well-established Ti:Sapphire laser.…”
