Ultra-compact solid-state lasers for next-gen handheld instruments
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 […]
Bulk-solid-state amplifier provides net gain only in a selected sub-region of the gain spectrum of a broad-bandwidth material. Parasitic emission outside the selected spectral range is suppressed. For ps, fs, and widely tunable lasers. Can make watt-level ASE sources with emission wavelengths at, near, or far away from net gain peaks. See Resources / White […]
Anthony Manni is a laser R&D and production scientist at JGMA. He holds a Bachelor of Science degree in Materials Science and Engineering from University of Connecticut (UConn).
June 2017 – JGMA has developed a compact and low-cost eyesafe laser that provides 2 to 6 mJ pulse energy. Pulse duration is 1 to 3 ns depending on pulse energy. The laser can be configured to provide any wavelength in the 1500 to 2000 nm range. Laser head size is 2.5″W x 2″L x […]
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 […]
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 […]
June 2015 – USPTO has issued to JGM Associates patent US 9,046,697 “Low speckle light sources and displays using multimode optical fiber”. This patent is available for licensing.
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. […]
May 2012 – Experimental data on a high-gain, high-energy VHGM MOPA was added to the Mini-MOPAs section. This MOPA generates >100 mJ with 5 mJ of 1064 nm seed energy and 35 mJ with 150 uJ seed energy. High-energy MOPAs.
