Abstract
(EN)
A solid laser device (100), comprising: a first laser module (110) configured to convert a first laser source into first laser; a first rotatable mirror (141) provided with a first mirror portion (1411), a second mirror portion (1412), and a third mirror portion (1413), the first rotatable mirror (141) being configured to, at a first position, reflect the first laser by means of the first mirror portion (1411), and at a second position, transmit the first laser by means of the second mirror portion (1412) and the third mirror portion (1413); a second laser module (120) configured to convert a second laser source into second laser; a second rotatable mirror (142) provided with a fourth mirror portion (1421) and a sixth mirror portion (1423), the second rotatable mirror (142) being configured to, at a third position, reflect the first laser by means of the sixth mirror portion (1423) and transmit the second laser by means of the fourth mirror portion (1421); and a third laser module (130) configured to convert the first laser and the second laser into third laser. By means of the method, laser of different wavelengths can be selected to be output, and the laser has high power intensity.
