A component of the laser that consists of two mirrors facing each other, which reflects light back and forth to amplify it within the lasing medium.

Creutzfeldt-Jakob disease (CJD) is a form of brain damage that leads to a rapid decrease of mental function and movement.

CJD is not a medical emergency, but early diagnosis and treatment may make the symptoms easier to control, allow patients time to make advance directives, and give families additional time to come to terms with the condition.

Gas lasers are a type of laser that uses a gas as the lasing medium, where the gas is excited to produce coherent light. These lasers are characterized by their ability to generate high-power output and are widely used in various applications, ranging from industrial cutting and welding to medical procedures and scientific research. The operation of gas lasers relies heavily on principles like population inversion and the control of gas flow and pressure to achieve efficient lasing.

A condition in which a higher energy state has more particles than a lower energy state, essential for achieving lasing action in lasers.
