Nanosecond Lasers

Nanosecond lasers emit optical pulses with durations in the range of 1 to 100 nanoseconds — delivering peak power levels orders of magnitude above continuous wave lasers at the same average power, enabling material processing, ranging, spectroscopy, and defense applications where high instantaneous intensity rather than sustained thermal energy determines system performance.

Q-switched Nd:YAG lasers are the most widely deployed nanosecond laser platform. A Q-switch — acousto-optic or electro-optic — stores energy in the gain medium during pumping then releases it as a single high-energy pulse in nanoseconds. Pulse energies on Q-switched Nd:YAG systems range from microjoules on compact OEM modules to several joules on laboratory and industrial systems. Peak powers reach megawatts to gigawatts. Fundamental output at 1,064nm converts to 532nm green, 355nm UV, and 266nm deep UV through nonlinear frequency doubling, tripling, and quadrupling crystals — giving a single laser source access to multiple wavelengths relevant to different applications.

Laser-induced breakdown spectroscopy (LIBS) uses nanosecond pulses focused to megawatt per square centimeter irradiance to ablate a microscopic surface sample and generate a plasma whose emission spectrum identifies elemental composition — used for explosive precursor detection, alloy verification, soil analysis, and forensic material identification. Rangefinders and target designators use nanosecond Nd:YAG pulses at 1,064nm to measure distance and illuminate targets for laser-guided munitions.

These lasers serve Pakistan’s defense electronics research programs at NESCOM and SUPARCO, university physics and chemistry departments conducting LIBS and laser spectroscopy research in Lahore and Karachi, Pakistan Ordnance Factories laser marking and component serialization operations, industrial laser cleaning contractors in Karachi, and Pakistan Aeronautical Complex laser rangefinder and designator maintenance programs.

Tactical Supply Pakistan supplies nanosecond lasers for LIBS spectroscopy, defense ranging, laser marking, industrial cleaning, and scientific research procurement across Pakistan.
