Abstract: A super continuum light source includes an input light source having semiconductor diodes generating an input beam having a wavelength shorter than 2.5 microns. Optical amplifiers receive the input beam and form an amplified optical beam having a spectral width. The optical amplifiers may include a cladding-pumped fiber amplifier doped with rare-earth materials. A nonlinear element may include mid-infrared fibers to receive the amplified optical beam and to broaden the spectral width of the received amplified optical beam to 100 nm or more through a nonlinear effect forming an output beam, wherein the output beam is pulsed. At least a portion of the output beam is in a mid-infrared wavelength range between 2 microns and 5 microns and at least a portion of the one or more mid-infrared fibers comprises a ZBLAN fluoride fiber coupled to a chalcogenide fiber.

Abstract: There is presented a spectroscopic apparatus and method wherein an input light source that inputs pump light to a photon pair source. The photon pair source converts pump photons into signal and idler photon pairs. The photon pair source is, in some of examples described herein, tuneable so that the wavelength of the signal and idler photons can be changed by application of a tuning means. At least one of the signal and idler photons is made incident upon a medium under test. A heralding detection apparatus is used to detect any signal and idler photons output from the spectroscopy apparatus, wherein at least one of the photons of the pair has interacted with or been operated upon by the medium under test.

Abstract: A spectral imaging device (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follow a beam path (16B) from the sample (10) to the image sensor (28). The refractive, optical element (24A) is spaced apart a separation distance (42) from the sample (10) along the beam path (16B). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), controls the mover assembly (29) (24C) to modulate the separation distance (42), and controls the image sensor (28) to capture the data.
