Thermal lasers vs. LILT

High power or thermal lasers can produce a substantial amount of heat. This destructive potential makes high power laser a key component in industrial applications such as cutting and welding. Thermal laser combines power and precision and therefore has many beneficial uses in surgical and ablative procedures.

Unlike thermal lasers, the low intensity laser beam is ‘soft power’, athermal and can stimulate cellular regeneration and natural healing. Red and infra-red lasers with power outputs in the range of 10 to 250 mW belong in this category, in addition to superluminous diodes up to the 2000mW level.

Low intensity laser energy stimulates cellular function at many levels including metabolism; in essence it promotes the initiation of multiple physiological and beneficial effects in the repair and function of human cells. LILT is widely used in the medical and cosmetic fields, principally because it is non-destructive to the target tissue­, while positively affecting many functions such as collagen formation, cellular metabolism, angiogenesis, lymphatic flow, etc.
