Claim 8:
9. A laser device for skin treatment, comprising:
a laser generating unit generating a pulse having an adjusted pulse width; and
a laser amplifying unit amplifying the pulse supplied from the laser generating unit,
wherein the laser amplifying unit comprises:
a first amplification medium for first amplifying the pulse supplied from the laser generating unit;
a first mirror adjusting a path of the pulse first amplified while passing through the first amplification medium;
a second mirror transmitting the pulse having the path adjusted by the first mirror to a second amplification medium;
the second amplification medium spaced apart from the first amplification medium and for second amplifying the pulse supplied from the second mirror;
a first pumping lamp spaced apart from the first amplification medium and the second amplification medium and illuminating the first amplification medium and the second amplification medium;
a second beam splitter allowing the second amplified pulse by the second amplification medium to pass;
a third mirror arranged to face the second amplification medium with the second beam splitter therebetween, to reflect the pulse second amplified while passing through the second amplification medium and passing through the second beam splitter and to adjust a path of the pulse;
a first wave plate arranged between the third mirror and the second beam splitter to change a polarization or phase of the pulse passing through the second beam splitter and directed to the third mirror;
a first beam splitter arranged to face the first mirror with the first amplification medium therebetween, to reflect the pulse having the path adjusted by the third mirror and to adjust a path of the pulse,
wherein the pulse having the path adjusted by the first beam splitter is third amplified while passing the first amplification medium, the third amplified pulse is directed to the second mirror while the path of the third amplified pulse is adjusted by the first mirror, the pulse having the path adjusted by the second mirror is directed to the second amplification medium, and the fourth amplified pulse while passing through the second amplification medium is sent out while the path of the fourth amplified pulse is adjusted by the second beam splitter, and
the pulse supplied from the laser generating unit transmits the first beam splitter and is directed to the first amplification medium.
