What is typically the characteristic of a solid-state laser compared to gas lasers?

Solid-state lasers are known for their better beam quality and stability when compared to gas lasers. This stems largely from their construction and the characteristics of the gain medium used. In solid-state lasers, the gain medium, typically a crystal or glass doped with rare-earth or transition metal ions, allows for a more coherent output. This coherence results in a more uniform and stable beam, making solid-state lasers particularly valuable in applications requiring precision, such as laser cutting or medical procedures.

In addition, the solid-state medium tends to exhibit lower thermal distortion under operation, which can contribute to beam stability. This property is vital for maintaining the quality of the laser beam over longer distances or when focused onto a target. As a result, the enhanced beam quality and stability of solid-state lasers make them preferred options for many advanced applications compared to gas lasers, which may exhibit more fluctuations or less coherence in their output.
