Abstract: Laser annealing apparatus includes a plurality of frequency- tripled solid-state lasers, each delivering an output beam of radiation at a wavelength between 340 nm and 360 nm. Each output beam has a beam-quality factor (M2) greater of than 50 in one transverse axis and greater than 20 in another transverse axis. The output beams are combined and formed into a line-beam that is projected on a substrate being annealed. Each output beam contributes to the length of the line-beam.

Abstract: An optical element includes an optical material including a first edge and an opposing second edge. The optical element further includes a plurality of micro-channels arranged within the optical material. Each of the micro-channels of the plurality of micro-channels extends from the first edge to the second edge of the optical material.

Abstract: Verstärker-Anordnung zur Steigerung von Leistung und Energie umfassend eine Multipasszelle und mindestens ein Verstärkungsmedium, wobei die Multipasszelle konkav gekrümmte Spiegel aufweist und das Verstärkungsmedium innerhalb der Multipasszelle derart angeordnet ist, dass die Pumpstrahlung das Verstärkungsmedium mehrfach durchläuft und von dem Verstärkungsmedium absorbiert wird, und wobei ein zu verstärkender Laserstrahl das Verstärkungsmedium durchläuft. Die Spiegel sind so ausgelegt und angeordnet, dass eine White-MuItipasszelle gebildet wird und die Pumpstrahlung und der zu verstärkende Laserstrahl große Querschnitte an den Positionen haben, an denen Spiegel und Verstärkungsmedien angeordnet sind. Es ist auch eine Anordnung vorgesehen, bei der ein hochreflektiver Spiegel und ein teiltransmissiver Spiegel vorgesehen sind, die im Zusammenwirken mit der Multipasszelle einen Laser-Resonator in Form eines Laser-Oszillators bilden.

Abstract: A laser system includes a laser diode that, upon activation, selectively produces a continuous wave of laser light or uniformly spaced, intermittent pulses of laser light. The system further includes a laser focuser with a plurality of lenses that focus the laser light produces by the laser diode and direct the laser light to an optical resonator. The optical resonator includes a lasing medium that, when intersected by the laser light from the laser diode, produces a beam of laser light with a wavelength that may be used for therapeutic treatment. The system is operable to produce the therapeutic laser light when the laser diode is operating in either the continuous wave mode or the pulsed mode, without moving components of the system relative to one another.

Abstract: An EUV radiation light source generation apparatus includes a pump laser, at least one pulse shaping unit, a wavelength conversion unit, and a high-order harmonics generation unit. The pump laser provides a pulse laser radiation beam. Each pulse shaping unit conducts a spectrum extending operation and a phase compensation operation to the pulse laser radiation beam. The phase compensation operation makes multiple frequency components of the pulse laser radiation beam emitted by the pulse shaping unit to be substantially in phase. The wavelength conversion unit conducts a center wavelength conversion operation to the pulse laser radiation beam. The high-order harmonics generation unit receives the pulse laser radiation beam processed by the pulse shaping unit and the center wavelength conversion operation, and focuses the received pulse laser radiation beam to a high order harmonic generation medium to generate a high order harmonic radiation beam.
