Patent number: 8724213Abstract: A High-power sum frequency generator system including a first electromagnetic source for generating a first fundamental field and a second fundamental field emitted along a propagation path, and a first nonlinear component and a second nonlinear component arranged in series along the propagation path. The first nonlinear component generates a first sum frequency field from the first fundamental field and the second fundamental field, the first sum frequency field having a first polarization. The second nonlinear component generates a second sum frequency field from the first and second fundamental fields, the second sum frequency field having a second polarization. The system has an output that includes the first sum frequency field and the second sum frequency field, and a direction of the first polarization forms a mutual angle with a direction of the second polarization such that the two polarizations are non-parallel.Type: GrantFiled: October 14, 2010Date of Patent: May 13, 2014Assignee: Advalight ApsInventors: Morten Thorhauge, Jesper Liltorp Mortensen, Jesper Rubech Rasmussen

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
