Gia công vật liệu không tiếp xúc bằng laser đã được ứng dụng nhiều trong thực tế. Đây là kỹ thuật hội tụ năng lượng ánh sáng công suất cao vào một diện tích nhỏ trên bề mặt chi tiết hay còn được gọi là phương pháp gia công cắt laser, hàn laser hoặc quét bề mặt...

Many practical uses have been proven by purposely controlling light propagation to achieve adequate non-contact effects on materials. Delivering high-power light into a small region on the materials’ surfaces, known as light focusing, allows us to perform several processing methods, such as laser cutting, welding, or scanning...
