    摘要: In a CO2 laser a pre-ionizer is assembled in a flange configured to be attached to a laser-gas enclosure of the laser over an aperture in a wall of the enclosure. An aperture in the base of the flange is aligned over the aperture in the enclosure wall. The aperture in the pre-ionizer flange is covered by a ceramic membrane. A disc electrode is in contact with the ceramic membrane on a side of the membrane outside of the laser-gas enclosure. An RF potential applied to the disc electrode creates a corona discharge on the side of the ceramic membrane inside the enclosure. The corona discharge ionizes laser gas in the enclosure before RF power is applied to electrodes of the slab laser.

    摘要: A RF shielded, series inductor, high power impedance matching network interconnector is provided for connecting an RF power supply to electrodes contained in the shielded, hermetically sealed laser tube housing of a slab laser system. The impedance matching interconnector comprises a short length of co-axial conductor and an impedance matching network that includes two L shaped networks. The inner conductor of the co-axial conductor is connected between the power supply output and the impedance matching network. The outer conductor of the co-axial conductor is grounded. The co-axial conductor has an impedance characteristic to match the power supply output impedance. The first L-shaped network includes a first inductor having a first end connected to the inner conductor of the co-axial conductor and a first capacitor connected to the second end of the first inductor and a second plate connected to ground. The second L shaped network includes a second inductor having a first end connected to the common connection between the second end of the first inductor and the first plate of the first capacitor and a second capacitor having a first plate connected to the second end of the second inductor and a second plate connected to ground. The common connection between the second end of the second inductor and the first plate of the second capacitor is connected through the shielded, hermetically sealed laser tube housing to the electrodes of the slab laser system. The two L-shaped networks may be implemented in a “single capacitor” configuration for lower power applications or in a “multi-capacitor” configuration for higher power applications.

    摘要: Various electro-optical modulator module designs are presented, which can provide for uniform, symmetric, and efficient heat removal for mode-locking, Q-switching, and/or cavity dumping operations. Heat can be uniformly extracted from an EO crystal without imposing undue stress, thereby preventing birefringence and laser beam degradation. A liquid-cooling approach can be used for high-duty operations, such as mode-locking operations. Efficient heat removal can prevent thermal run-away from electrical heating of the crystal due to the large drop in the electrical resistance of CdTe with increasing temperature when operated above 50° C. RF or video arcing and subsequent damage to the EO crystal can be prevented by surrounding the crystal with a low dielectric constant material that lowers the capacitance coupling to ground, while still maintaining good thermal cooling.
