Foil-only
Supplied as a single dye acetate Q-switch foil for applications requiring a foil-only configuration.
- Compact and lightweight
- Lower overall thickness than the sandwich construction
- Suitable where a foil-only Q-switch arrangement is required
Passive Q-Switches
Dye Acetate Q-Switch Foil
We manufacture dye acetate passive Q-switch foils for selected small Nd:YAG pulsed laser heads.
- Germany-based B2B supplier
- Manufacturing to customer specifications
- Optical inspection and measurement support
- From single components to repeat orders
Product overview
This passive Q-switch foil supports typical pulse widths of 10–15 ns and short-pulse, high-peak-power operation in a compact, lightweight format without requiring an external driver or power supply.
This type of passive Q-switch foil was previously supplied by companies such as Kodak and used in various earlier Nd:YAG laser systems. As it has become increasingly difficult to source, it is particularly relevant for the replacement, repair, and maintenance of legacy laser equipment.

Configurations
Sandwich construction
The dye acetate foil is mounted between two SCHOTT N-FK5 glass substrates.
- Can be a more suitable option for higher-repetition-rate or higher-power laser applications
- Greater overall thickness than foil-only supply
- Higher cost than foil-only supply
