What is Laser Design and Applications?
Laser Design and Applications is the development and utilization of electric discharge pumped lasers, particularly those employing atomic iodine and singlet oxygen generation for continuous wave operation and gain measurement, alongside copper vapor lasers, frequency conversion, and high power laser technology.
This field encompasses 868,818 works with a focus on electric discharge mechanisms, laser oscillation, and atomic iodine systems. Key areas include singlet oxygen generation for oxygen-iodine lasers and gain measurement techniques for continuous wave operation. Research also addresses copper vapor lasers, frequency conversion processes, and high power laser configurations.

Why It Matters
Laser Design and Applications enables inertial confinement fusion through indirect-drive approaches, as detailed in 'Development of the indirect-drive approach to inertial confinement fusion and the target physics basis for ignition and gain' (1995) by J. D. Lindl, which outlines capsule designs for thermonuclear fuel confinement achieving efficient burn conditions with 2466 citations. High-power lasers support laser compression of matter to super-high densities for thermonuclear applications, per 'Laser Compression of Matter to Super-High Densities: Thermonuclear (CTR) Applications' (1972) by J. Nuckolls et al., with 1887 citations. Recent advancements include fluid-based laser scanning for brain imaging using electrowetting prisms, as in Optics Express work by Eduardo Miscles and Mo Zohrabi, and IMR's €1.3m funding for 5-axis CNC systems with nanosecond and femtosecond lasers for advanced manufacturing.
