    摘要： A carbon-dioxide CO2 gas-discharge laser is energized by the output a radio-frequency power supply (RFPS). Output-power of the laser is stabilized by adjustments of the RFPS responsive to periodic measurements of the laser output-power using detector output amplified by an amplifier. The amplifier has an offset-voltage which is subject to drift. A synchronous auto-zero arrangement is provided for canceling out the offset-voltage of the amplifier immediately prior to each periodic measurement of the laser output power.

    摘要： An RF powered CO2 gas-discharge laser includes discharge electrodes and a lasing gas mixture between the electrode. The lasing gas mixture is ionized when the RF power is applied to the electrodes and laser action is initiated when the RF power has been applied for a duration sufficient to ignite a discharge in the lasing gas mixture. The gas mixture is pre-ionized by periodically applying the RF power to the electrodes for a predetermined period during which ignition of a discharge is not expected to occur. RF power reflected back from the electrodes is monitored. If the monitored power falls below a predetermined level indicative of the imminent onset of laser action before the predetermined duration has elapsed, application of the RF power to the electrodes is terminated to prevent the laser action from occurring.

    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： A gas discharge laser including a lasing gas between discharge electrodes and has a power supply for generating RF pulses to be delivered to the electrodes of the laser for energizing the lasing gas. A sequence of RF simmer pulses is delivered to the electrodes. The simmer pulses create sufficient free electrons in the lasing gas to facilitate subsequent ignition of the discharge while not causing laser action. RF lasing pulses having a longer duration than the simmer pulses are delivered to the electrodes to ignite the discharge and provide corresponding laser output pulses. Delivery of the simmer pulses is suspended during delivery of the lasing pulses to avoid amplitude or pulse-width modulation of the laser output pulses by the simmer pulses.

    摘要： The quality of pulses output from laser systems such as super-pulsed CO2 slab lasers can be improved using half-wavelength electro-optic modulators (EOMs), in combination with thin film polarizers (TFPs). A voltage applied across a CdTe crystal of the EOM rotates the polarization of a pulse passing through the EOM by 90°. The polarization determines whether the pulse passes through, or is redirected by, the TFP. The voltage applied to the crystal can be pulsed to prevent a drop in charge, which could allow radiation to leak to the application. A totem pole switch used to apply voltage to the EOM can receive a pulsed voltage for improved performance. Directing by the EOM allows pulses to be clipped at the front/back end(s), split into portions, and/or directed to separate scanners. Directing pulses or pulse portions to different scanners can increase the output of systems such as hole drilling systems.
