Breck Hitz

Solid-state laser sources at the argon-ion wavelength of 488 nm find many applications in medicine, graphics, semiconductor inspection and elsewhere. Several commercial models are already available, and others are expected to be introduced to the market soon. Figure 1. A frequency-doubled fiber-laser master oscillator power amplifier generates 18.1 mW of 488-nm light. The current products are based on a frequency-doubled diode laser, but now researchers from the University of Southampton in the UK and from the Royal Institute of Technology in Stockholm, Sweden, have demonstrated a...Read full article

    solid-state laser
    A solid-state laser is a type of laser that uses a solid gain medium (as opposed to a liquid or gas) to produce coherent light. The term "solid-state" refers to the fact that the active medium, where the lasing action occurs, is a solid material. This material is typically a crystalline or glass-like substance doped with specific ions or atoms that can undergo stimulated emission to generate laser light. The basic components of a solid-state laser include: Gain medium: This is the solid...
