Solid-State Laser•Light Amplification by Stimulation Emission Radiation.
• Crystalline solid Amplifying medium.
• Ruby, ( doped )• Titanium Sapphire, (Ti doped )• Neodymium: Yttrium Lithium Fluoride, (Nd doped YLi)• Neodymium: Yttrium Vanadate laser, (Nd doped YV)• Alexandrite, ( doped Be)
Properties of crystalline solid
• Higher density gain.
• Good optical and thermal properties.
• Dopants’ ions are chosen for their specific radiative properties.
• Rare-earth ions (neodymium, erbium, holmium, thulium, europium)• Transition metals ions (chromium, titanium, nickel, cobalt, copper)• Actinide ions (Actinium, Thorium, Uranium, Plutonium, Einsteinium)
Working’s fundamentals
• Population inversion
• Spontaneous Emission
• Stimulated Emission
