1. A method for manufacturing a polymeric stent, comprising: manufacturing the polymeric stent by forming a pattern on a polylactic acid tube with a second harmonic generator laser in which a wavelength of 940 nm to 1,552 nm is converted,
wherein a pulse width of the second harmonic generator laser is 1 fs to 900 fs and a repetition rate of the second harmonic generator is 2 kHz to 200 kHz.
