“…However, to benefit from a high gain from this architecture, the diameter of the SCF should be 1 mm or below what is hardly obtainable by Czochralski or ceramic techniques. Fortunately, the micro-pulling-down crystal growth is now a mature technique remarkably suited for the production of long (up to 1 m) and thin (down to 300 μm diameter) Yb:YAG SCFs with laser optical quality [5]. Interesting laser performances have been reported in cw and Q-switched Yb:YAG SCF oscillators [6].…”

“…Single-crystal fibers have a small diameter (typically 1 mm or below) and a length of several centimeters. The optical quality of the barrel surface is good enough to efficiently guide the light, for example, from a high power laser diode in end-pumped configuration [1,2]. Many different processes enable to make such specifically shaped single crystals among them, Czochralski method is the best known to grow bulk single crystal but requires complicated after-grown processes or shaping to reach small geometries.…”

“…In the last few years, a great interest appeared in single-crystal fiber lasers to improve thermal management and increase laser power [1,2]. Single-crystal fibers have a small diameter (typically 1 mm or below) and a length of several centimeters.…”

“…A intensidade dos fótons Y em um dado ponto i do difratograma pode ser calculada através da equação (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22), que é descrita em função dos índices de Miller (k) em uma dada reflexão de Bragg, da radiação de fundo yb; do fator A de absorção dos fótons pela amostra; de uma função PK que leva em consideração a textura da amostra; de uma função ϕ que descreve o perfil de reflexão em relação a sua direção; do fator de estrutura FK (posições atômicas no cristal), de uma função LK composta pelos fatores de Lorentz, de polarização e de multiplicidade; e finalmente de um fator de escala estritamente relacionado a propriedades do feixe com o qual se trabalha…”

“…Além disso, o potencial químico descreve a taxa líquida de associação dos átomos nos sítios ativos de crescimento que é função da variação de entropia do material (eq. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Quanto maior a variação de entropia, menor a taxa de associação dos átomos na interface.…”
