Article summary:
1. Structured light fields have a variety of applications, such as optical micromanipulation, optical communication, imaging, processing, and measurement.
2. Structured light can be generated with extra-cavity methods or intra-cavity methods. Intra-cavity methods have higher efficiency and beam purity than extra-cavity methods.
3. Digital lasers based on SLMs and DMDs are capable of producing structured light beams on demand with high speed and stability.
