How can environmental conditions like humidity affect laser operation?

Environmental conditions, particularly humidity, can greatly influence the performance and stability of various types of lasers. High humidity levels can lead to increased scattering and absorption of the laser beam in the atmosphere, which can reduce the effective range and overall output of the laser. Additionally, certain lasers may be sensitive to moisture in the air, potentially causing alterations in their optical components or functions.

For example, solid-state lasers or gas lasers may experience changes in their output characteristics due to humidity levels since these factors can influence cooling, optics, or even the lasing medium itself. Therefore, understanding how humidity and other environmental factors affect laser operation is crucial for maintaining optimal performance in practical applications, making the correct answer relevant in the context of laser safety and operational protocols.
