High Energy (High Power) half-wave (HWP) and quarter-wave (QWP) Waveplates

Half-wave plates (HWP) for high energy applications

Half-wave plates (HWP) for high-energy applications work by rotating the polarization of high-power laser beams. Specific construction allows Alien Photonics HWPs to an withstand the intense conditions of high-power laser systems, such as those used in industrial processing, medical treatments, and scientific research, ensuring optimal performance and safety.

Quarter-wave plates (HWP) for high energy applications

Quarter-wave plates (QWP) for high-energy applications convert linearly polarized light into circular polarization or vice versa in high-power laser systems. Alien Photonics QWPs are indispensable in advanced optical setups, including optical communications, laser machining, and experimental physics, where precise polarization manipulation is crucial under high-energy conditions.

High Energy Waveplates for powerful lasers

High laser induced damage threshold waveplates: air-spaced, bonded and single waveplates

The most laser energy resistant construction is air-spaced or just simple single plate design. Optical contact (bonding) construction also offers good threshold values. However, glued(cemented) types have limited LIDT characteristic, due to the glue characteristics.

High LIDT air-spaced waveplates

Air-spaced high power waveplates are constructed by fixing two low (or multiple) order waveplates into a mount, with precisely designed air gap between them. This air gap also acts as thermal insulator between plates and reduces chance of potential thermal gradients. Alien Photonics air-spaced high energy waveplates typically LIDT characteristic is 10-20 J/cm² @ 1064 nm, 10 ns, 10 Hz.

Optically contacted (bonded) waveplates for high power applications

Two low (or multiple) order waveplates bonded together. Optical contact method creates a solid connection between plates without the need for adhesive materials. The absence of adhesives eliminates potential sources of optical absorption and heat generation at the bonding interface, significantly increasing the waveplate's resistance to laser-induced damage. Typical LIDT is 10-20 J/cm² @ 1064 nm, 10 ns, 10 Hz.

Laser damage resistant monolithic single wave plates

Single waveplates have simplest construction – just one plate! Lack of glue and generally thicker (except true zero order waveplates) makes them more resistant to temperature changes and increase laser induced damage threshold. LIDT of these single plates is typically 10-20 J/cm² @ 1064 nm, 10 ns, 10 Hz.
