“…Both emissions have possible applications in opto-communication, biomedical diagnostics, sensors and lidar system [1][2][3][4]. Till now, the Er 3 þ ion has demonstrated laser operations in various Er 3 þ -doped crystals and glasses [5][6][7][8][9][10].…”

“…Er 3+ is well known as one of the most interesting laser ions with optical transitions from infrared (IR) to ultraviolet for potential applications in medicine, optical communications and IR distance measurements 19–24. However, the relatively low concentration of Er 3+ ions due to a quenching effect definitely limits the luminescence efficiency.…”

“…As a result of this effort the first Er:YAG laser was made to operate in 1975, working in long pulse and in Q-switching regimes [7]; the first actively mode-locked system was reported in 1982 [8]. In the search for higher and higher efficiency, several other hosts for the Er3 ion have been investigated, and in particular Er:YAIO3 [9,10], Er:YLF [11,12], Cr,Er:YSGG [11,[13][14][15][16]. Since the time of early experimentation the relevance of a high Er3 doping concentration (30%-50% [7]) has been recognized; presently the standard concentration is set around 50% for the Er:YAG active material.…”
