A ruby rod
Theodore Maiman built the first working laser using a ruby rod while working at Hughes Research Laboratories in Malibu, California. It lased for the first time on May 16, 1960.

Is active material and gain medium in lasers the same?
No, they are not the same. The active material in a laser is the substance that emits the light when stimulated, while the gain medium is the part of the laser that amplifies the light passing through it. The gain medium is typically made of the active material along with other components to enhance the laser's performance.
What is active medium in laser?
The active medium in a laser is the material that generates light amplification through stimulated emission of radiation. This material typically consists of atoms or molecules that can be excited by an external energy source to emit coherent light. Common examples of active mediums are gases (such as helium and neon), solid-state materials (like crystals or glass), and semiconductors (such as gallium arsenide).
Why ruby laser is a solid state laser?
laser production is done by a solid state active working material.
What are the conditions for laser?
The conditions for laser operation include having an active medium to generate light amplification by stimulated emission of radiation, a mechanism for pumping energy into the active medium, and mirrors to create optical feedback to sustain laser oscillation.
Who discovered the laser?
The first working laser was demonstrated by Theodore Maiman at Hughes Research Labs on May 16th, 1960.
Who built the first LASER?
The first laser was built by Theodore H. Maiman in 1960 at Hughes Research Laboratories. The laser used a ruby crystal as the gain medium and produced a red laser beam.
What day was the laser invented?
1960- this was the first working laser, but it had been a theory since 1917.
When was the laser first introduced?
The first working laser was introduced in 1960. Initially used to treat diseases and disorders of the eye,
What is semiconductor laser?
A semiconductor laser is a type of laser which utilizes a semiconductor as its Photon source, rather than a gas (Argon, CO2, Etc...) laser which uses inert gas as an active medium. Many physicists and engineers consider a semiconductor laser a type of "Solid-State" or "Two-State" LASER.
What is the role of He gas in He Ne laser?
Helium gas serves as the active medium in a He-Ne laser. It provides population inversion between energy levels, allowing for laser action. The helium gas helps to excited the neon atoms to produce laser light at a wavelength of 632.8 nm.
What is active region in laser?
active region
When was the first laser cutter invented?
American physicist Theodore Maiman constructed the first working laser in 1960. But research started in 1958
