Publication number: 20220173568Abstract: The system and method of using an ultra-short pulse mid and long wave infrared laser. The system is seeded with a 2 ?m laser source having a pulse duration in the femtosecond range. The beam is stretched, to increase the pulse duration, and the beam is amplified, to increase an energy level of the laser beam. Both mid wave IR and long wave IR seed beams are first generated, and then amplified via one or more optical parametric chirped-pulse amplification stages. A compressor may be used to compress one or more of the output beams to achieve high peak power and controllable pulse duration in the output beams.

Patent number: 9407059Abstract: Techniques and architecture are disclosed for providing a laser system. In one specific example embodiment, the system includes a thulium-doped fiber laser coupled by silica glass fiber to a remote optical converter (ROC) including a Ho:YAG laser and, optionally, an optical parametric oscillator (OPO) utilizing in germanium phosphide (ZnGeP2; ZGP) or orientation-patterned gallium arsenide (OPGaAs). The fiber laser may emit a low-peak-power, continuous wave pump signal that pumps the Ho:YAG laser, which in turn emits a higher-peak-power, pulsed signal. When included, the OPO can be used to convert the resultant, pulsed signal to a longer wavelength (e.g., about 2-5 ?m, or greater). In some cases, distributed architecture and reduced weight/bulk may be realized while eliminating the need to actively cool the ROC for operation, for example, over a broad temperature range (e.g., ?55-125° C.). Also, methods of preparing high-peak-power, pulsed signals using such systems are disclosed.Type: GrantFiled: February 24, 2015Date of Patent: August 2, 2016Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Leonard A.

Patent number: 8194310Abstract: An all fiber mid-IR pulse generator is disclosed that may be used to drive an external non-linear converter. The generator comprises fiber laser oscillator and fiber amplifier elements wherein diode lasers are used to cladding pump the different fiber elements depending on different configurations of the pulse generator. Gain switching of the fiber lasers precludes the need for discrete devices such as Q-switches to generate pulses. The fiber laser and fiber amplifier elements are all fused together, along with fiber isolators and reflective gratings, so there is no free space coupling, and there are no optical elements except as may be needed to couple the output of the generator to a non-linear converter. The all fiber implementation has a single transverse mode at the lowest order mode of operation which results in a nearly diffraction limited output which causes non-linear converters to operate more efficiently.Type: GrantFiled: May 3, 2009Date of Patent: June 5, 2012Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Peter A Ketteridge, Peter A Budni, Daniel J Creeden

Patent number: 7286587Abstract: A Ho:YAG crystal laser is disclosed which is doped with less than 2% holmium to reduce the lasing threshold and up-conversion, thereby increasing the operating efficiency of the laser. The laser does not need sensitizer ions so energy mismatches introduced by the sensitizer ions ale eliminated to the thereby increase the efficiency of the laser while minimizing detrimental thermal loading in the laser caused by up-conversion loss processes. The Ho:YAG crystal laser is directly pumped by a Thulium fiber laser at 1.9 ?m at the holmium 5I7 to 5I8 transition to produce an output at 2.1 ?m yielding a very low quantum defect. The laser is embodied as a thulium fiber laser pumped oscillator or an amplifier.Type: GrantFiled: January 5, 2005Date of Patent: October 23, 2007Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Peter A.

Patent number: 7170909Abstract: A directly pumped, un-sensitized, holmium, quasi-two level fiber laser is disclosed that is doped with Holmium active ions between 0.1 and 2.0 percent by atomic weight. This yields greater energy efficiency from the laser because up-conversion losses are minimized, mismatches created by sensitizer ions are eliminated by having no sensitizer ions, and thermal loading of the fiber medium of the laser is thereby reduced. In addition, the pump ratio of the fiber laser is 0.9 which yields a very low quantum defect. The low doping percentage of holmium active ions also eliminates any absorption of its own energy because the power of the diode pumping source is sufficient to cause the laser to reach transparency.Type: GrantFiled: May 25, 2004Date of Patent: January 30, 2007Assignee: Bae Systems Information and Electronic Systems Integration Inc.Inventors: Peter A.
