Dermatological treatment device with one or more laser diode bar

A dermatological treatment device, comprising:

• a device body having an application end configured to be placed in contact with a skin surface;
• a laser diode bar having multiple emitters configured to generate laser radiation for delivery to the skin surface;
• a power source and control electronics configured to provide power to the laser diode bar such that the each emitter of the laser diode bar simultaneously generates and emits a discrete laser beamlet;
• wherein the device includes no optics downstream of the laser diode bar, and
• wherein the laser diode bar is arranged with respect to the application end of the device body such that with the application end of the device body arranged in contact with the skin surface, the discrete beamlets simultaneously emitted by the multiple emitters combine before reaching the skin surface to form an instantaneous collective beam that provides an instantaneous contiguous treatment zone at the skin surface for a dermatological treatment.

A dermatological treatment device, comprising:

• a device body having an application end including a skin-contacting surface configured to be placed in contact with a skin surface;
• a laser diode bar having multiple emitters configured to generate laser radiation for delivery to the skin surface via the application end of the device body;
• a power source and control electronics configured to provide power to the laser diode bar such that each emitter of the laser diode bar generates and emits a discrete laser beamlet;
• wherein the laser diode bar is arranged with respect to the application end of the device body such that with the application end of the device body arranged in contact with the skin surface, (a) an emitting surface of the laser diode bar is spaced from the skin surface by less than 5 mm, and (b) the discrete beamlets emitted by the multiple emitters combine before reaching an output plane defined by the skin-contacting surface of the device to form a collective beam at the output plane that defines a contiguous irradiated area at the skin surface for a dermatological treatment;
• wherein the application end is configured to be moved across the skin surface during delivery of the collective beam to the skin surface to form a contiguous treatment zone defined by a travel of the contiguous irradiated area due to the movement of the application end across the skin.

A dermatological treatment device, comprising:

• a device body having an application end including a skin-contacting surface configured to be placed in contact with a skin surface during treatment;
• a laser diode bar having multiple emitters configured to generate laser radiation for delivery to the skin surface, the laser diode bar having a fill factor of at least 50%;
• a power source;
• control electronics configured to provide power from the power source to the laser diode bar such that each emitter of the laser diode bar generates and emits a discrete laser beamlet;
• wherein the device includes, downstream of the laser diode bar, only an open air interface, a window, or other structure that does not deflect or influence the angular distribution profile of the emitted laser beamlets;
• and
• wherein the laser diode bar is arranged with respect to the application end of the device body such that with the application end of the device body arranged in contact with the skin surface, the discrete beamlets emitted by the multiple emitters combine before reaching an output plane defined by the skin-contacting surface of the device to form a collective beam at the output plane that provides a contiguous treatment zone at the skin surface to provide a dermatological treatment.
