RESUMO

In this work we present the development of a laser system based on an Er:YLF Brewster cut crystal with 15mol% erbium at the yttrium site, emitting at 3 m and pumped by a laser diode emitting at 975 nm. Using this system we obtained 1,80(18) W peak power when operating in the quasi-continuous regime. The cavity is optimized for medical applications and to operate at maximum power when pumped with 250 s pulse duration. The unique temporal behavior of this laser was subject of this study for the first time, as the optimization of the maximum output power as a function of the pulse duration. There are differences in the intrinsic mechanism of the laser when it is operated in pulsed or cw condition, especially with respect to the effect of the W22 energy transfer upconverssion parameter which value in the literature is very divergent. The estimated value of this process was also obtained in this work and is 2,0x10-16 cm3/s.
