The experiment was conducted using a neody-mium glass laser modified for normal pulse operation. The energy density was varied from 850J/sq cm where no breakdown occurred to 5000J/sq cm where the threshold for breakdown was exceeded. The normal pulse duration was 600μS.

When the USS Ponce steams into the Arabian Gulf next year, it will have a far less costly tool at its disposal: it will be the first warship with a laser weapon, the US Office of Naval Research has revealed. Developed by Raytheon Missile Systems, based in Tucson AZ, the Laser Weapon System (LaWS) will be able to track and destroy drones or explosives ...

The evaluation of the direct beam laser hazards primarily consists of the determination of the NOHD with and without the use of optical devices, and the necessary optical density (OD) required for laser eye protection. The required OD would depend on whether the viewer was located at the laser exit or at a location downrange from the laser.
