1. 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; and
a first mirror arranged to reflect the laser pulse first amplified while passing through the first amplification medium and to return the first amplified laser pulse in a direction of the first amplification medium;
a first beam splitter arranged to face the first mirror with the first amplification medium therebetween and to adjust a path of the pulse second amplified while returning to and passing through the first amplification medium;
a first wave plate arranged between the first mirror and the first beam splitter to change a polarization or phase of the passing pulse;
a second mirror transmitting the pulse having the path adjusted by the first beam splitter to a second amplification medium;
the second amplification medium spaced apart from the first amplification medium and for third 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 third mirror arranged to face the second mirror with the second amplification medium therebetween, to reflect the pulse third amplified while passing through the second amplification medium and to adjust a path of the third amplified pulse;
a fourth mirror transmitting the pulse having the path adjusted by the third mirror to a third amplification medium;
a third amplification medium for fourth amplifying the pulse supplied from the fourth mirror;
a fifth mirror arranged to face the fourth mirror with the third amplification medium therebetween, to reflect the pulse fourth amplified while passing through the third amplification medium and to adjust a path of the fourth amplified pulse;
a sixth mirror transmitting the pulse having the path adjusted by the fifth mirror to a fourth amplification medium;
a fourth amplification medium for fifth amplifying the pulse supplied from the sixth mirror;
a second pumping lamp spaced apart from the third amplification medium and the fourth amplification medium and illuminating the third amplification medium and the fourth amplification medium; and
a seventh mirror arranged to face the sixth mirror with the fourth amplification medium therebetween, to reflect the pulse passing through the fourth amplification medium and to adjust a path of the pulse, and
wherein the pulse supplied from the laser generating unit transmits the first beam splitter and is directed to the first amplification medium.
