Israel's Defense Ministry unveils breakthrough laser technology

In the Jerusalem Post, Anna Ahronheim reports,
The Defense Ministry has made a technological breakthrough in the development of lasers that can intercept aerial threats, including rockets and anti-tank guided missiles, it announced Wednesday.Read more here.
New laser technology “makes the security apparatus more lethal, more powerful and more advanced,” Defense Minister Naftali Bennett said Wednesday evening.
...The breakthrough recently made by the ministry is based on the precision of the laser beam, which can be focused on long-range targets and which can overcome atmospheric disturbances such as clouds and dust storms.
...They will also allow for a decrease in the number of missile interceptors used and the future potential to intercept a variety of threats, including unmanned aerial vehicles, drones and guided rockets.
...As a result of the breakthrough, the ministry has launched three programs for the development of high-energy laser demonstration systems in cooperation with the two companies: a ground-based laser system to complement the capabilities of the Iron Dome, development of a maneuverable platform-mounted laser system to defend troops in the field and the development of a laser demo system mounted on an air platform to intercept threats above cloud covers and for the defense of wide areas.

"If as a child I had known that “senior fellow for Laser and Sensor Systems” would become a real job, my education might have followed a much different path."
So writes Stephen Green at Instapundit, as he links to this CNBC story.

"We have shown that a powerful directed energy laser is now sufficiently light-weight, low volume and reliable enough to be deployed on tactical vehicles for defensive applications on land, at sea and in the air," said Robert Afzal, senior fellow for Laser and Sensor Systems at Lockheed.
According to Afzal, the Lockheed Martin team created a laser beam that was near "diffraction limited," meaning it was close to the maximum limit for focusing energy toward a single, small spot.
Lockheed believe the laser will act as a complementary weapon on the battlefield and will prove particularly effective in disabling drones or incoming rockets.
In 2015, the company used a 30kW laser weapon, known as ATHENA, to disable a truck sited a mile away.
Solid state laser technology is seen as a cheap option to defend against incoming attacks.
A Patriot missile, usually priced at about $3 million was recently used to shoot down a $200 quadcopter drone, according to a US general.
Conversely, in 2015 the Navy estimated that a solid-state laser can be fired for less than one dollar per shot.
Lockheed says it is now preparing to ship the "combined fiber" laser to a U.S. Army Command center in Alabama.

Needed: Laser control
Lindsey Bever reports in the Washington Post that
Federal authorities have launched an investigation after numerous aircraft were hit by laser beams Wednesday night.Read more here.
More than 20 aircraft were struck while in flight over at least 16 U.S. cities, according to a statement from the Federal Aviation Administration. Authorities said three laser strikes were reported to the FAA in the New York City area, followed by three near Dallas that hit jets as they were preparing to land.
“None of the pilots reported injuries,” authorities said in a statement to The Post. “Nevertheless, shining a laser at an aircraft is a federal crime that the U.S. vigorously pursues. Lasers distract pilots from their safety duties and can lead to temporary blindness during critical phases of flight, such as takeoff and landing. In some cases in the past, pilots have reported eye injuries that required medical treatment.”
