Latest Patents

Gaidarenko's latest patents include innovative designs aimed at improving gas discharge lasers. One of his patents, titled "Gas discharge laser long life electrodes," describes a laser chamber with two elongated erodable electrode elements. These elements are designed to minimize turbulence in the discharge region while allowing for gradual erosion over more than 8 billion pulses. The system includes a pulse power mechanism that delivers electrical pulses of at least 2J at rates of at least 2 KHz, along with a blower that circulates laser gas at speeds of at least 2 m/s. Additionally, a heat exchanger is incorporated to manage the heat generated by the blower and discharges.

Another significant patent is "Electric discharge laser with acoustic chirp correction." This invention addresses the issue of wavelength chirp in high pulse rate gas discharge lithography lasers. Gaidarenko identifies pressure waves from discharges as a major cause of this problem. His solution involves structural changes within the laser chamber to moderate these pressure waves and maintain a consistent laser gas temperature, thereby reducing variations in the index of refraction and improving beam direction stability.
