Filed:

Feb 22, 2011

Appl. No.:

13/032143

Inventors:

Scott Howard - Ithaca NY, US
Anthony Hoffman - Princeton NJ, US

Assignee:

GK TECHCOM LLC - Gladstone NJ

International Classification:

H01S 3/23
H01S 3/10

US Classification:

372 3801, 372 3802

Abstract:

A laser system is proposed that is configured to provide a pseudo-CW signal at room temperature. The system utilizes an array of pulsed lasers that are controlled (in terms of turning “on” and “off”) to provide, in combination, a quasi-CW output signal. The activation of each individual laser is controlled to turn “on” and “off” in a predefined sequence, where at least one laser is “on” at any given point in time. Thus, by combining the outputs from the plurality of pulsed lasers onto a single output signal path, the resultant output signal from the system will be a pseudo-CW signal (the amount of “ripple” present in the signal controlled by factors such as the number of individual lasers in the plurality of lasers, the duty cycle of each individual laser, etc.). The duty cycle of the individual lasers can be controlled to provide a high power output signal (higher duty cycle), or provide a high wall-plug efficiency of the system (lower duty cycle).

International Classification:

G02B 26/10

US Classification:

3591981

Abstract:

An optical scanner, scanner apparatus, or scanner assembly, which may be particularly advantageous for use in a multiphoton microscope, includes a first drivable bending component, a second drivable bending component mounted perpendicularly to the first component, and at least one optical waveguide coupled one or both of the first and second bending components, wherein the at least one optical waveguide provides both a propagation path for a multiphoton excitation radiation delivery between a light source and a target and a multiphoton-induced emission radiation delivery between the target and a detector. A GRIN relay lens. A multiphoton microscope incorporating the scanner and the GRIN relay lens.

US Classification:

2504591, 359238, 2502081

Abstract:

A fluorescence emission imaging method and apparatus allows for high frame rate imaging in scattering medium as well as for fluorescence, phosphorescence, or luminescence lifetime imaging, time-resolved fluorescence, phosphorescence, or luminescence lifetime spectroscopy and imaging. A method involves providing an illumination beam, propagating the illumination beam to a light modulator array, modulating the illumination beam so as to generate an array of point sources, wherein each of the point sources is modulated at a frequency, imaging the modulated illumination beam on the object, and detecting a fluorescent, phosphorescent, or luminescent emission from the object. An optical imaging component in the form of a modulation mask has multiple bands. Each band has alternating transmissive and/or reflective and/or absorptive regions that are patterned such that light scanned over a band will be modulated at a band-related frequency.
