| 20120230356 | SCALABLE, EFFICIENT LASER SYSTEMS - A laser comprises an end pump light source and a gain medium having a first end, a second end, and four sides comprising a first, a second, a third, and a fourth side. The end pump light source is optically coupled to the first end and pumps the gain medium. The first side and the third side are tapered inwardly from the first end to the first end to the second end at a taper angle β relative to a longitudinal lasing axis and have a polished finish capable of reflecting light inside the gain medium. The second side and the fourth side are substantially parallel to the longitudinal lasing axis have a ground blasted finish. The first side is also tilted inwardly at a slant angle α from the fourth side to the second side. A laser beam R | 09-13-2012 |
| 20120314724 | Miniaturized Laser Amplifier Arrangement Having a Pump Source - A laser amplifier arrangement includes an optical pump source and an axially arranged laser oscillator-amplifier configuration pumped by the pump radiation. The laser oscillator-amplifier configuration includes a laser oscillator excitable by a portion of the pump radiation to emit a laser beam, and a laser amplifier that amplifies the laser beam using the pump radiation. The laser oscillator and laser amplifier are arranged in a substantially coaxial or collinear manner relative to a longitudinal axis of the laser oscillator-amplifier configuration. The pump source includes a first beam source for producing a first pump radiation to pump the laser oscillator, a second beam source for producing a second pump radiation for the laser amplifier, and a pump radiation conducting device, by means of which both the first and the second pump radiation can be lead into the laser oscillator-amplifier configuration substantially in the direction of the longitudinal axis for longitudinal pumping. | 12-13-2012 |
| 20130148679 | OPTICAL PUMPING OF A SOLID-STATE GAIN-MEDIUM USING A DIODE-LASER BAR STACK WITH INDIVIDUALLY ADDRESSABLE BARS - A diode-laser bar stack includes a plurality of diode-laser bars having different temperature dependent peak-emission wavelengths. The stack is arranged such that the bars can be separately powered. This allows one or more of the bars to be “on” while others are “off”. A switching arrangement is described for selectively turning bars on or off, responsive to a signal representative of the temperature of the diode-laser bar stack, for providing a desired total emission spectrum. | 06-13-2013 |

| 20150030045 | NOISE DETECTION, DIAGNOSTICS, AND CONTROL OF MODELOCKED LASERS - The present invention features a laser based system configured with a noise detection unit. The system includes a mode-locked oscillator. A noise detection unit includes at least one optical detector that monitors optical pulses generated by the mode-locked oscillator and produces an electrical signal in response to the optical pulses. The noise detection unit includes a first filter to transmit signal power over a signal bandwidth which includes the mode-locked laser repetition frequency, frep. The noise detection unit may include one or more filters to transmit power over a noise bandwidth that substantially excludes repetition frequency, frep. Non-linear signal processing equipment is utilized to generate one or more signals representative of the power in the signal bandwidth relative to the power in the noise bandwidth. The system includes a controller operable to generate a signal for controlling the laser based system based on the relative power. | 01-29-2015 |
