February 2018 – A compact pulsed 2950 nm laser developed by JGM Associates Inc. (JGMA; Burlington, MA), and its use for biological mass spectrometry imaging, are described in a February 2018 on-line publication in Analytical and Bioanalytical Chemistry (Springer): Characterization of a novel miniaturized burst-mode infrared laser system for IR-MALDESI mass spectrometry imaging. The paper’s […]
January 2018 – JGM Associates (JGMA; Burlington, MA) has received notification of award from DoD/SOCOM for a Phase I SBIR program entitled “Daytime Markers / Designators.” The project will develop ultra-compact, mJ-level, mid-IR OPOs with near-diffraction-limited beam quality, suitable for use in next-generation man-portable markers, designators, and rangefinders. The SBIR program is designed to overlap […]
June 2017 – JGMA has announced development of a compact and low-cost eyesafe laser that provides 6 mJ pulse energy at pulse rates to 50 Hz. Pulse duration is about 1 ns. The laser can be configured to provide any wavelength in the 1500 to 2000 nm range. Laser head size is 2″W x 2″L […]
February 2017 – JGMA has developed a low-cost and compact 355 nm laser for UV-MALDI and similar applications. The laser prototype generates more than 20 uJ of 355 nm pulse energy at pulse rates to 25 kHz (>500 mW average) with cw pumping, and at pulse rates from 100 Hz to 10 kHz with quasi-cw […]
January 2017 – JGM Associates announced it has, to date, manufactured and delivered more than 250 lasers to a leading supplier of handheld LIBS and other spectro-analytical instruments. This on-going OEM laser business represents the first of a growing list of custom, compact, and low-cost OEM laser products that JGMA is developing for handheld and […]
February 2016 – JGM Associates, Inc. (JGMA; Burlington, MA) has announced a patent-pending bulk-solid-state laser amplifier design having a “tailored” gain spectrum. It is based on the company’s patented diode-pumped wedged-slab (VHGM) gain module technology. In the new design, the two HR coatings that establish the zig-zag seed beam path through the VHGM slab have […]
October 2015 – JGM Associates announced that it has entered into an exclusive agreement to supply OEM lasers to a leading manufacturer of handheld LIBS and other spectroscopy instruments. JGMA’s patent-pending ultra-compact and low-cost laser design improves LIBS performance over a wide ambient temperature range and reduces or eliminates the need for sample surface preparation.
June 2015 – USPTO has issued to JGM Associates patent US 9,046,697 “Low speckle light sources and displays using multimode optical fiber”. JGMA plans to develop low-speckle red, green, and blue light sources for laser cinema and other large-venue projection display applications, but is also willing to license this technology.
June 2014 – JGM Associates has developed a high-energy and low-cost laser that generates >3 mJ /pulse at a 1-micron wavelength. Beam quality is good enough to consistently break down air on every pulse. Laser head size is 1″ x 1″ x 2″. The ultra-compact OEM laser will be useful for laser-induced breakdown spectroscopy (LIBS) and related laser-spark applications.
October 2013 – JG Manni’s book Basic Aspects of Medical and Dental Lasers is now available at Amazon.com in paperback. Paperback and eBook versions are available at Lulu.com, and eBook versions are available at Apple’s iBookstore and Barnes and Noble. The book provides tutorials for the non-laser-technical reader on how lasers are designed and used clinically for surgical applications and in laser dentistry. […]
