ABSTRACT:
A laser device, comprising a laser beam emitter having an optical resonator, wherein the optical resonator has a resonator and a reflection mirror, and at least one of a length of the resonator or a curvature of the reflection mirror is determined so as to satisfy condition that a parameter M2of beam quality of a projected laser beam is within a range of 8≦M2≦22, where M2=πW·Θ/λ (W is a beam waist of a laser beam; Θ is a spreading angle; and λ is a wavelength of the laser beam).
