Two functionally important differences exist between the diode laser and the carbon dioxide (CO2) laser (used more commonly in small animal surgery). Diode laser energy is delivered through a quartz fiber instead of being reflected through an articulated arm or waveguide. Quartz fibers are generally more flexible and resilient than waveguides and can be inserted through an endoscope for minimally invasive procedures. Laser-tissue interaction is the other significant difference. The CO2 laser is completely absorbed by water, which limits the effect to visible tissue. The diode wavelength is minimally absorbed by water and may affect tissue as deep as 10 mm below the surface in the free-beam mode. With proper respect for the tissue effect, these differences can be used to the advantage of the patient.
二极管激光器与二氧化碳（CO2）激光器（更常用于小动物手术）之间存在两个功能上的重要差异。二极管激光能量通过石英光纤传输，而不是通过关节臂或波导反射。石英光纤通常比波导更灵活且更具弹性，并且可以通过内窥镜插入以进行微创手术。激光与组织的相互作用是另一个显著差异。CO2激光完全被水吸收，这将其作用限制在可见组织。二极管激光波长被水的吸收极小，在自由光束模式下可能会影响到表面以下深达10毫米的组织。在充分考虑组织效应的情况下，这些差异可被用于患者的益处。
