Abstract: A laser sustained plasma lamp includes a mechanically sealed pressurized chamber assembly (330) configured to contain an ionizable material. The chamber assembly is bounded by a chamber tube (310), an ingress sapphire window (340), a first metal seal ring (320) configured to seal against the chamber tube ingress end and the ingress sapphire window, an egress sapphire window (342), and a second metal seal ring (322) configured to seal against the chamber tube egress end and the egress sapphire window. A mechanical clamping structure (350, 355) external to the chamber assembly is configured to clamp across at least a portion of the ingress sapphire window and the egress sapphire window. The ingress sapphire window and the egress sapphire window are not connected to the chamber tube via welding and/or brazing.
