Patent number: 10753795Abstract: The invention provides an infrared upconversion spectrometer for determining a mid-IR spectrum of received infrared light with a high resolution. The spectrometer applies upconversion to transform light in the mid-IR to the near-IR range where efficient detectors are available. The up-conversion causes divergence of the light, and in addition, the invention applies an extra dispersive element to record a spectrum.Type: GrantFiled: July 7, 2017Date of Patent: August 25, 2020Assignee: DANMARKS TEKNISKE UNIVERSITETInventors: Christian Pedersen, Peter Tidemand-Lichtenberg, Jeppe Seidelin Dam, Lasse Høgstedt

Patent number: 9529244Abstract: The present invention relates to a system and a method for processing electromagnetic radiation. In particular, the present invention relates to conversion of light, such as light (28) comprising image information (34), from one wavelength interval to another wavelength interval. More in particular, the present invention relates to wavelength conversion of incident light (28) by means of optical mixing with a laser beam in a non-linear crystal (14). The method according to the present invention comprises receiving incoming electromagnetic radiation (28) and a laser beam (12) in a non-linear crystal, setting a plurality of phase match conditions within the non-linear crystal (14), obtaining a plurality of images of the processed electromagnetic radiation (30), and providing a first combined image (42) comprising a first part of a first image and comprising a second part of a second image.Type: GrantFiled: June 28, 2012Date of Patent: December 27, 2016Assignee: DANMARKS TEKNISKE UNIVERSITETInventors: Jeppe Seidelin Dam, Peter Tidemand-Lichtenberg, Knud Palmelund Sørensen, Christian Pedersen

Patent number: 9410846Abstract: A multi-channel infrared spectrometer for detecting an infrared spectrum of light received from an object. The spectrometer comprises a wavelength converter system comprising a nonlinear material and having an input side and an output side. The wavelength converter system comprises at least a first up-conversion channel and a second up-conversion channel, and is arranged such that light traversing the wavelength converter system at different angles in the nonlinear material is imaged into different positions in an image plane. The first up-conversion channel is configurable for phase-matching infrared light in a first input wavelength range incident on the first side and light in a first output wavelength range output on the second side, and correspondingly, the second up-conversion channel is configurable for phase-matching infrared light in a second input wavelength range incident on the first side into light in a second output wavelength range output on the second side.Type: GrantFiled: July 9, 2014Date of Patent: August 9, 2016Assignee: Danmarks Tekniske UniversitetInventors: Peter Tidemand-Lichtenberg, Jeppe Seidelin Dam, Christian Pedersen

Patent number: 7961772Abstract: A laser system according to the invention comprises pump generating means (x02, x03) for generating at least a first and a second, preferably focused, pump beam, and lasing means (x06, x07) for emitting radiation by being appropriately pumped. The lasing means (x06, x07) is disposed in a first resonator so as to receive the first pump beam in order to generate a first beam (x21) having a first frequency, and the lasing means (x06, x07) is disposed in a second resonator so as to receive the second pump beam in order to generate a second beam (x22) having a second frequency. At least one Q-switch (x08; x17, x18) is disposed in the first and the second resonator, so that the first beam and the second beam both pass a Q-switch (x08; x17, x18). The laser system (x01) has an output (x13) generated from said first beam (x21) and said second beam (x22), and at least a part of said output (x13) is fed back to a regulation system (x14), said regulation system (x14) controlling said pump generating means (x02, x03).Type: GrantFiled: July 10, 2007Date of Patent: June 14, 2011Assignee: AdvalightInventors: Peter Tidemand-Lichtenberg, Morten Thorhauge, Jesper Liltorp Mortensen
