In recent years, we witnessed the use of laser weapons in naval conflicts in the Persian Gulf, the Strait of Hormuz and the Sea of Oman. Conflicts that are not armed and under the laws of hostilities and the rights of war are not considered, and the use of laser weapons in them violates the principles of proportionality and necessity in international humanitarian law. Based on the Fourth Protocol of 1995 of the 1980 on Conventional Weapons and Article 86 of International Customary Humanitarian Law, the use of blinding and permanently blinding laser weapons is prohibited. Based on Article 36 of the 1st Additional Protocol of 1977, the governments in the production and use of new weapons should ensure that they are not prohibited from the point of view of international rules.the use of laser weapons in the aforementioned maritime conflicts is a violation of international obligations and has a criminal nature, and according to Article 2 of the 2001 international responsibility plan of governments, it causes the international responsibility of the governments that use it. The main goal of this research is to analyze the international responsibility of governments in using laser weapons in maritime conflicts in the Persian Gulf and the Sea of Oman. Therefore, by using an applied research with a descriptive-analytical method to collect the data obtained through library studies and field investigation, we have sought to realize this goal. The result of the research showed that laser weapons are a violation of international obligations in the field of intimidation, unnecessary pain and suffering, use by terrorist groups, intelligent murder,violation of the right to life and the right to reproduction. humanitarian rights, human rights and mandatory rules and universal obligations are international and are considered an international violation and cause the international responsibility of governments.
