Abstract
A fiber arrangement, in particular for providing broadband light, preferably in the ultraviolet frequency range, comprises: a hollow core optical fiber (11), and at least one housing (15) having a chamber (27) in which a piezo device (25) is arranged, the piezo device (25) having a variable length and the chamber (27) being in fluid communication with a hollow core (13) of the fiber (11) such that a change of length of the piezo device (25) causes a change of the size of a volume (23) which is provided by the hollow core (13) and the chamber (27) for a fluid, such as a gas or a mixture of gases.
Claims19
A fiber arrangement for providing broadband light, comprising:
- a hollow core optical fiber, and
- at least one housing having a chamber in which a piezo device is arranged, the piezo device having a variable length and the chamber being in fluid communication with a hollow core of the fiber such that a change of length of the piezo device causes a change of the size of a volume which is provided by the hollow core and the chamber for a fluid, such as a gas or a mixture of gases.
An optical system for providing broadband light, the optical system comprising:
- a fiber arrangement, the fiber arrangement comprising:
- (i) a hollow core optical fiber, and (ii) at least one housing having a chamber in which a piezo device is arranged, the piezo device having a variable length and the chamber being in fluid communication with a hollow core of the fiber such that a change of length of the piezo device causes a change of the size of a volume which is provided by the hollow core and the chamber for a fluid, such as a gas or a mixture of gases;
- a pulsed laser source for providing laser pulses to the fiber arrangement;
- and
- at least one piezo driver for driving the piezo device arranged in at least one housing of the fiber arrangement.
A method of generating broadband light in the UV frequency range, with an optical system, the optical system comprising (a) a fiber arrangement, the fiber arrangement comprising:
- (i) a hollow core optical fiber, and (ii) at least one housing having a chamber in which a piezo device is arranged, the piezo device having a variable length and the chamber being in fluid communication with a hollow core of the fiber such that a change of length of the piezo device causes a change of the size of a volume which is provided by the hollow core and the chamber for a fluid, such as a gas or a mixture of gases;
- (b) a pulsed laser source for providing laser pulses to the fiber arrangement;
- and (c) at least one piezo driver for driving the piezo device arranged in at least one housing of the fiber arrangement, the method comprising:
- inputting laser pulses into the fiber arrangement to generate broadband pulses, which are output by the fiber arrangement,
- while inputting the laser pulses, controlling the piezo device arranged in the at least one housing to generate the broadband pulses with a desired frequency spectrum or to generate the broadband pulses such that different pulses comprise different frequency spectra.
