What role do chromophores play in laser therapy?

Chromophores play a crucial role in laser therapy as they are substances that absorb specific wavelengths of light. This selective absorption is essential because it allows the laser's energy to be directed toward particular tissues or structures within the body. By targeting areas with chromophores, clinicians can achieve desired therapeutic effects, such as reducing pain, promoting healing, or destroying unwanted tissue. The ability of chromophores to absorb light at designated wavelengths ensures that the laser energy is used efficiently, enhancing the effectiveness of the treatment while minimizing damage to surrounding tissues. In contrast, other aspects mentioned, such as enhancing brightness, providing cooling effects, or determining the type of laser, do not capture the primary function of chromophores in this context.
