A method of creating a tissue effect at a tissue site delivers electromagnetic energy through a skin surface from an electromagnetic energy delivery device coupled to an electromagnetic energy source. At least one of the electromagnetic energy delivery device or electromagnetic energy source includes a memory. A reverse thermal gradient is created through the skin surface to sufficiently heat an underlying tissue site to provide that a temperature of the skin surface is lower than a temperature of the underlying tissue. Information is stored from the memory to facilitate operation of at least one of the electromagnetic energy delivery device or the electromagnetic energy source. Electromagnetic energy is applied through the skin surface to the underlying tissue. A tissue effect is created on at least a portion of the tissue site.

Method and kit for treatment of tissue

The present invention provides an excimer laser capable of producing a high quality pulsed laser beam at pulse rates of about 4,000 Hz at pulse energies of about 5mJ or greater. A preferred embodiments is an ArF excimer laser specifically designed as a light source for integrated circuit lithography. An improved wavemeter with special software monitors output beam parameters and controls a very fast PZT driven tuning mirror and the pulse power charging voltage to maintain wavelength and pulse energy within desired limits. In a preferred embodiment two fan motors drive a single tangential fan which provides sufficient gas flow to clear discharge debris from the discharge region during the approximately 0.25 milliseconds between pulses.

FOUR KHz GAS DISCHARGE LASER

A pulse forming network or capacitor load is charged to a precise voltage from an energy storing device with a circuit including a transformer having a primary connected in series with a switch and storage device and a secondary connected in series with the load and a monitor circuit. The monitor circuit develops an output signal indicative of the load voltage and current. In response to the output signal increasing to a predetermined value the switch is opened. The transformer, having a substantial leakage inductance, releases its stored energy when the switch is opened. The transformer stored energy is coupled to the load and to a capacitor connected to the primary. Charge stored in the capacitor after the load requirements have been satisfied is transferred back to the energy storage device.
