Diode pumped CW and passively Q-switched Nd:LGGG laser at 1062 nm

“…LGGG than the crystal Nd:GGG [10,11]. At the same time, the properties of the mode locked also have been reported in the crystal Nd:GYSGG [12,13].…”

Passively Q-switched performance of a Nd:Gd3Ga5O12 eye-safe laser at 14234 nm with Co2+:LaMgAl11O19 as saturable absorber

“…The relationship between the effective cavity length L and the optical cavity length L opt is given by L opt − L ln − 1∕n, where l is the length of the gain medium and n is the refractive index of the gain medium. The thermal focal length can be expressed as [7] where f th is the thermal focal length, dn∕dT is the temperature-dependent change in the refractive index of the crystal, n is the refractive index, α T is the thermal expansion coefficient, K C is the thermal conductivity of the crystal, ω p is the beam radius of the pump laser, L c is the length of the crystal, P in is the pump power, and ξ is the thermal conversion coefficient, In the calculation, the thermal conversion coefficient in Nd:GGG was estimated as 0.3. The other parameters used in the calculation are listed in Table 2.…”

“…Recently, our attention has been focused on the Nd:GGG crystal. This is because, compared with the Nd:YAG single crystal, Nd:GGG possesses several advantages, including a lower laser pumped threshold [7][8][9][10][11][12], a better mechanic property [7,8,10,13], and a larger thermal capacity [9,11,13]. Previously, most of the research on Nd:GGG lasers was focused on the wavelengths of 1062 nm [6,7,9,13], 938 nm [8,10], and 1331 nm [11,14].…”

Passively mode-locked Nd:GGG laser with a semiconductor saturable absorber mirror

“…The GGG crystal has been proved to be the best host for the solid state heat capacity lasers (SSHCL) [13][14][15][16]. The spectral and thermal properties, continuous wave (CW), passively Q switched laser operation of the Nd:GGG crystal have been researched more [17][18][19][20][21][22][23][24][25][26]. Until recently, to our knowledge the mode locking of the Nd:GGG crystal with SESAM was only researched by Qin et al [27].…”
