Nous étudions le potentiel de la fibre à cristaux photoniques (PCF) pour réaliser une transmission de haute qualité et à haute puissance. Nous utilisons le PCF avec une structure de trous d'air quasi-uniforme et clarifions numériquement que le PCF quasi-uniforme peut réaliser la surface effective (Aeff) d'environ 500µm2 avec une perte par courbure comparable à celle d'une fibre monomode conventionnelle à usage télécom en considérant la transmission quasi monomode. Nous appliquons ensuite le PCF quasi-uniforme à la délivrance d’un faisceau haute puissance de classe kW pour le traitement laser monomode. La conception transversale du PCF avec un potentiel de fourniture de puissance élevée de plus de 300 kW·m est révélée numériquement et expérimentalement. Un faisceau monomode de 10 kW à 1070 30 nm est délivré avec succès sur un câble à fibre optique de XNUMX m de long contenant un PCF fabriqué avec une qualité de faisceau de classe monomode de M.2 =1.7 pour la première fois.

Abstract: We investigate the potential of photonic crystal fiber (PCF) to realize high quality and high-power transmission. We utilize the PCF with a quasi-uniform air-hole structure, and numerically clarify that the quasi-uniform PCF can realize the effective area (Aeff) of about 500µm2 with bending loss comparable with that of a conventional single-mode fiber for telecom use by considering the quasi single-mode transmission. We then apply the quasi-uniform PCF to kW-class high-power beam delivery for the single-mode laser processing. The cross-sectional design of the PCF with the high-power delivery potential of more than 300kW·m is numerically and experimentally revealed. A 10kW single-mode beam at 1070nm is successfully delivered over a 30m-long optical fiber cable containing a fabricated PCF with single-mode class beam quality of M2 =1.7 for the first time.
