Cr4+:YAG/Polymer nanocomposite as alternative materials for Q-switched lasers: properties, modeling, and applications

Objective

The development and application of solid-state lasers (SSRs) over the last decade, emphasizing their wide-ranging uses in fields such as metal processing, medical applications, and optical transmission systems. It outlines the fundamental components of SSRs and the importance of achieving a balance between gains and losses in the laser resonator for effective generation. The concept of Q-switching is introduced, highlighting its role in enhancing laser performance by modulating the Q-factor of the resonator. Active and passive Q-switching methods are compared, with a focus on the advantages of passive Q-switches for generating powerful sub-nanosecond pulses in compact laser systems. The challenges associated with finding suitable passive Q-switching materials, particularly for long-term use, are discussed, leading to the proposal of a novel approach using a composite structure of polymer matrix with Cr4+:YAG nanopowders. This initiative, undertaken by the ALTER-Q consortium comprising European academic institutions, research organizations, and SMEs, aims to address the current limitations and pave the way for cost-effective alternatives in Q-switched laser technology.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
