Claim:
1. A laser system comprising: an oscillation unit to generate a laser output; a connection unit to connect the oscillation unit with an optical fiber loop; an amplifying unit to amplify the laser output on the optical fiber loop; a conversion unit disposed on a path of the optical fiber loop to convert pulsed wave laser output into continuous wave laser output; and an output unit disposed between the connection unit and the conversion unit to split a part of the laser output toward the conversion unit, wherein the laser output is repeatedly amplified by the amplifying unit while circulating the optical fiber loop, wherein the output unit is a connection unit to split a part of the laser output, the connection unit splits the laser output at a ratio of 90:10 to 50:50, and a ratio of an input port and an output port is 1:2 or 2:2, wherein the conversion unit comprises dispersion fiber having a high dispersion value, the dispersion fiber generates pulse dispersion of continuous wave laser output, and the dispersion fiber is connected to one end of the output unit to determine a dispersion amount according to a pulse repetition rate and an entire wavelength band.
