A laser machining mechanism comprises a laser source, an adjusting device, a lens set, a focusing lens set and an observation device. The adjusting device changes traveling direction of a laser beam emitting from the laser source to form a focused beam. The lens set allows the focused beam to propagate through a predetermined distance to emit without substantially reducing energy consumption. The focusing lens set makes the focused beam that emits from the lens set focused to form a machining beam projected to a workpiece to be machined. The observation device receives a reference image directly from the workpiece to be machined and a machined image obtained after the machining beam is projected to the workpiece to be machined. The laser machining mechanism for carrying out a sequence of machining operations on a set of workiece according to the present invention allows the observation device to receive the reference image and the machined image, thus the direct visual observation and correction can be immedi
