Lasers provide boon for manufacturing of ceremonial Thai umbrellas

Seen atop pagodas, inside Buddhist ordination halls, and in royal palaces, the tiered umbrella is one of Thailand's oldest and most sacred ornamental symbols. Constructing one of these ornate pieces, also called chatras, can take master artisans up to six months.

In the Journal of Laser Applications, researchers demonstrate a technique for constructing seven-tiered umbrellas using high-powered lasers, dramatically reducing the production time. Employing carbon dioxide lasers, they were able to fashion umbrellas from stainless steel in a matter of days while preserving their intricate beauty.

"At present, the craftsmen who make tiered umbrellas have become scarce," said author Pichet Limsuwan. "We hope to show a new way we can help conserve arts and culture in Thailand."
