Title:
EXTERNAL CAVITY LASER
Document Type and Number:
WIPO Patent Application WO/2022/267356
Kind Code:
A1
Abstract:
An external cavity laser (100, 200), comprising a resonant cavity, the resonant cavity comprising a first cavity surface (11) and a second cavity surface (61). A gain chip (1) is provided in the resonant cavity; a focusing lens (4) is further provided between the gain chip (1) and the second cavity surface (61); a light beam emitted by the gain chip (1) is converged onto the second cavity surface (61) through the focusing lens (4), and resonates between the first cavity surface (11) and the second cavity surface (61), wherein a gap is formed between the focusing lens (4) and the second cavity surface (61). The external cavity laser (100, 200) can achieve the technical effects of increasing the coupling tolerance of the focusing lens (4) in the resonant cavity, saving the space occupied by the resonant cavity, and improving the output optical power of the resonant cavity.
