摘要： Apparatus and methods are disclosed for amplifying an energy beam such as a beam of laser light or a charged particle beam. An exemplary method includes providing a liner having a first end, a second end, a liner axis, and a lumen extending along the liner axis and being bound by interior reflective walls of the liner. An energy beam is introduced into the first end of the liner. The beam propagates through the lumen from the first end to the second end as the beam reflects multiple times from the interior walls of the liner. Meanwhile, an implosive force is applied to the liner. The implosive force compresses the interior walls implosively toward the liner axis in a manner that amplifies the beam as the beam propagates through the lumen of the imploding liner. The amplified energy beam can be used for any of various purposes including ignition of a fusion target.

摘要： Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device (e.g., a Pockels cell) positioned along the optical axis of the resonator.

摘要： A long wavelength infrared laser system is disclosed where radiation from laser sources such as frequency-doubled Nd:YAG or a Cr:LiSAF is used to resonantly pump a gain medium consisting of a holmium-doped fluoride crystal having a high active ion concentration. The laser pump source has a pulse duration that may be short enough to gain switch a particular transition or long enough to allow end-pumping with high energy densities without damage. The gain material has an absorption approximately resonant with the pump source wavelength, and the dopant concentration is selected to maximize absorption strength for a given excitation. The output radiation from the laser system consists of one or more wavelengths including, in particular 3.9 nullm but also other infrared wavelgths such as 1.4 nullm, 2.9 nullm and 3.4 nullm., several of which may be produced simultaneousely from the same laser material through the mechanism of cascade transitions.

摘要： An optical amplifier comprises an active fiber (1), a pump unit (2) spaced from the active fiber and adapted to give a nominal, continuous pump power in an operational state, and a pump fiber (3) adapted to transfer optical pump power from the pump unit (2) to the active fiber (1). Moreover, in a safety state, the pump unit (2) is adapted to give a pulsed pump power whose mean power is lower than a prescribed safety limit. A method of preventing emission of optical power exceeding a prescribed safety limit on interruption of an optical fiber (3) which transfers pump power from a pump unit (2) to an active fiber (1), comprises changing the mean power of the pump power in response to a signal received from the active fiber (1) so that the mean power assumes a value below said safety limit if said signal is not received, and assumes a nominal value if said signal is received.

摘要： An all-optical flat panel display system is based on the generation of photoluminescence within a doped, optical waveguide display matrix. Color photoluminescence is produced through an infrared, two-step photonic upconversion process and the subsequent radiative emission process. Established principles of solid-state laser design and electronic upconversion in a host glass substrate are applied. The present photoluminescent display technology provides for flat-panel display systems having luminous output efficiencies approaching 67 lumens/Watt. That efficiency increase results from employing efficient, innovative photoluminescent phosphors and from an optical cavity architecture which enhances the three physical process (row excitation, column excitation and spontaneous output emission) operating inside the pixel. The present system is thinner, lighter weight, more power efficient and more cost competitive to produce than existing technologies. Further advantages realized by the present system include high readability in varying lighting conditions, viewing angle independence, size scalability without brightness and color quality sacrifice, rugged solid-state construction, vibration and thermal insensitivity and size independence. The present invention has potential applications in military, personal computing and digital HDTV systems, multi-media, medical and broadband imaging displays and large-screen display systems. Defense applications may range from full-color, high-resolution, see-through binocular displays to 60 inch digital command center displays.
