[0032] Such as figure 1 , figure 2 , image 3 as well as Figure 4 As shown, the embodiment of the present application provides a supercontinuum laser output device. The supercontinuum laser output device is a supercontinuum laser output head, which is used to receive pulsed light with high peak power transmitted by an external armored optical fiber. High peak power pulsed light pumps the photonic crystal fiber to generate supercontinuum laser and output the generated supercontinuum laser. The supercontinuum laser output device includes a substrate 10 and a photonic crystal fiber 20, the upper surface of the substrate 10 is provided with a first part 101 and a second part 102 distributed at intervals, the second part 102 can be expressed as the output device produces The output port of the supercontinuum laser, the output end of the photonic crystal fiber 20 is set at the second part 102 .

[0033] At this time, the setting of the first part 101 includes the following two...

Abstract

The application provides a supercontinuum laser output device and system, the supercontinuum laser output device includes: a substrate, the upper surface of the substrate is provided with a first part and a second part distributed at intervals, the first part and the second part Have different heights relative to the substrate; a photonic crystal fiber, which spirals on the upper surface of the substrate in a curved shape, and the input end and output end of the photonic crystal fiber are respectively arranged at the first part and the second part To form a height difference, the photonic crystal fiber is used to receive the high peak power pulsed light transmitted by the external optical fiber through the input end, and form a supercontinuum laser according to the high peak power pulsed light to transmit to the The second part is emitted to the outside through the second part.

Description

technical field [0001] The present application relates to the technical field of supercontinuum laser, in particular to a supercontinuum laser output device and system. Background technique [0002] The existing fiber laser output device (i.e., the output head) design is mainly applicable to a single specific wavelength fiber laser and cannot be applied to high-power supercontinuum fiber lasers. The reason is that the output head configuration of high-power supercontinuum lasers , in addition to satisfying the output function, it is also necessary to realize the generation of the supercontinuum, and the current fiber laser output device cannot take into account both the generation and output functions of the supercontinuum. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a supercontinuum laser output device and system, which is used to solve the problem that the existing fiber laser output device cannot take into ac...
