Abstract
A cordless, hand-held dermatologic hair-regrowth-inhibiting apparatus may include: a self-contained housing configured for gripping by a person's hand for cordless manipulation in a hair-regrowth-inhibiting procedure; a light source comprising one or more diode laser bars within the housing; a direct drive electrical circuit within the housing comprising one or more batteries for energizing the light source to produce output light pulses, wherein the electrical circuit does not include any storage capacitors that energize the light source by capacitor discharge; and a light path within the housing including an aperture through which the output light pulses are propagated out of the housing having properties sufficient for at least temporary hair-regrowth inhibition.
