Company Description
Kigre, Inc. Introduces: New Compact Q-switched Eye-Safe Lasers High Efficiency Side Pumped (HESP) Diode Pumped Solid State (DPSS) Laser Design. For nearly four decades Kigre has been a leader in solid state laser technology. Kigre has recently developed next generation megawatt class erbium glass (1534nm) eye-safe micro-lasers for use in enhanced laser surveillance, remote sensing, LIBS and chemical detection. The lasers utilize a unique pumping architecture that provides a foundation for rugged, compact and reliable high power/high gain devices an order of magnitude lighter, smaller, more efficient and less expensive than the existing state-of-the-art. Significant performance improvement is due to the invention of a of athermal high-gain laser glass materials and innovative conduction cooled packages that portend long diode lifetime at high power levels with minimal thermal conditioning requirements. HESP laser technology is enhancing both old and new government programs. Numerous contractors have already initiated integration of the small high power diode pumped solid-state lasers into various laser systems. Our new family of HESP lasers includes smaller passive Q-switched units such as the MK-11 head with a size of 0.65” x 1.2” x 1.3” and providing ~ 1mj, 6ns, 1Hz. Larger units include HESP A-O Q-switched head with a size of 1.4"x 2.2"x 5.0" and providing ~ 10-15mj, 6ns, 10-15Hz.

| New HESP-E-AO-6-10-15 10Hz, ~10-15mj, 6ns AO/Q-Switched Laser
Kigre is now offering a compact high efficiency Diode Pumped Solid-State (DPSS) Eye-Safe erbium glass laser designated (HESP-E-AO-6-10-15). The laser produces ~10-15mj Q-switched pulses at a wavelength of 1534nm. The laser active A-O Q-switch produces ~ 6ns pulses at up to 15Hz. Example performance over temperature (-30 Deg. C to + 50 Deg. C.) of great than 10mj energy at 10Hz pulse rep-rate.
For almost four decades Kigre has been a leader in solid state laser technology. Kigre has recently developed the next generation megawatt class erbium glass micro-lasers for use in enhanced laser surveillance, laser chemical detection, laser spectroscopy, range-gated imaging, range-finding, collision avoidance and other detection systems. The lasers utilize a unique pumping architecture that provides a foundation for rugged, compact and reliable high power/high gain laser devices an order of magnitude lighter, smaller, more efficient and less expensive than the existing state-of-the-art.
The significant performance improvement in these High Efficiency Side Pumped (HESP) Diode Pumped Solid State (DPSS) lasers is due in large part to the invention of a new generation of athermal high-gain laser glass materials and innovative conduction cooled packages that portend long pump diode lifetime at high power levels with minimal thermal requirements. HESP laser technology is enhancing both old and new government programs. Numerous contractors have already initiated the integration of the small high power diode pumped solid-state lasers into various laser systems.

| New High Power AO Q-Switched Erbium Glass Eye-Safe Laser
New HESP-E-6-10 10Hz, 15mJ, 6ns, 1535nm Diode Pumped Solid State (DPSS) Eye-Safe Micro-Laser
The first AO-Q-Switched HESP-E-6-10 10Hz (~15mj @ 10Hz, 6ns) laser has a head about the size of a cigarette pack and emits a non-blinding laser light at a wavelength of 1.54 microns. Useful for a laser pointer? Well, not exactly. Try a laser rangefinder, laser radar, LIBS, remote sensing or Flash LIDAR range-gated imaging with improved accuracy, range and resolution. The laser’s 10Hz pulse repetition frequency is readily adapted to video frame rate fractions of 50 or 60Hz in laser imaging applications.
Kigre, Inc. (Hilton Head Island, SC, USA), has developed a new family of eye-safe HESP (High Efficiency Side Pumped) lasers that are smaller, more efficient, 3 to 50 times faster and produce 6 times the peak power than the existing state-of-the-art. The lasers contain proprietary high strength rare earth doped laser glass materials with superior mechanical, chemical, thermal and optical properties for use as the gain elements in DPSS HESP lasers.
High peak power Q-switched lasers operating in the narrow spectral window between 1.5 and 1.6 micron are approximately 8000 times more “eye-safe” than other laser devices operating in the visible and near infrared. For example, a laser operating at 1.54 micron may emit Q-switched pulses with up to 7.9mj of energy and still be considered a Class I laser with no laser eye protection required.
Kigre’s laser glass combines the high strength properties typically associated with crystal laser materials, with attributes superior to crystals such as broad absorption bandwidth, and high solubility for rare earth ions. Unlike crystals, glasses are readily fabricated into complex clad and unclad gain elements containing high rare earth oxide concentrations. |
| New HESP-E-7-60 1-60Hz, 6-20mJ, 7ns, 1535nm DPSS Laser
The HESP-E-7-60 1-60Hz (~10mj @ 10Hz, 7ns) laser head is about the size of a cigarette pack and emits a non-blinding laser light at a wavelength of 1.54 microns. Useful for a laser pointer? Well, not exactly. Try a laser rangefinder, laser radar, LIBS, remote sensing or Flash LIDAR range-gated imaging with improved accuracy, range and resolution. The laser’s 30Hz (or 25Hz) pulse repetition frequency is readily adapted to half video frame rate in laser imaging applications.
