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 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 […]

Bulk-solid-state laser amplifier with “tailored” gain spectrum

  February 2016 – JGM Associates, Inc. (JGMA; Burlington, MA) has announced a 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 different […]
