Q-Switch

- Very low resonance operation with the AC voltage, only a few % greater than the DC switch-out voltage.

- No thermal blooming or photo-refractive damage.

- Typical contrast ratios of >2000:1 without high temperature degradation and high average powers more than 100 watts.

- Low insertion loss of 3 ~ 2% inside the Laser cavity.

- Extremely small capacitance (~2pF), giving a very fast rise-time (<220 psec) in a lumped element 50 ohm system.

- Material damage threshold is more than 4 GW/cm2 typical @ 1064nm for a 10ns pulse.

- And is limited by the AR coating.

- Can operate with average High Voltage as much as 1KV without electrode migration.

- Usable for pulse extraction from UV (200nm) to Mid-IR (2000nm).

- Cells with larger apertures up to 6 mm are available with 8.8KV quarterwave voltage at 1064 nm.
