Pulsed lasers for biological mass spectrometry imaging

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 […]

JGMA wins Phase I award to develop mid-IR OPOs with high beam quality

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 […]

JGMA has announced development of a compact and low-cost eyesafe laser

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 […]

JGMA has developed a low-cost and compact 355 nm laser for

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 […]

JGM Associates, Inc. (JGMA; Burlington, MA) has announced a patent-pending bulk-solid-state laser amplifier design

  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 […]

JGM Associates announced that it has entered into an exclusive agreement to supply OEM lasers to

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.

USPTO has issued to JGM Associates patent US 9,046,697

June 2015 – USPTO has issued to JGM Associates patent US 9,046,697 “Low speckle light sources and displays using multimode optical fiber”.
