XeCl laser pumped iodine laser using t-C4F9I [PDF]

open access: yes
An iodine photodissociation laser using t-C4F9I as the active material was pumped by an XeCl laser. An iodine laser output energy of 3 mJ with pulse duration of 25 ns was obtained when the pumping pulse energy was 80 mJ, the iodide pressure was 70 torr ...

Traveling-Wave Photomixers Based On Noncollinear Optical/Terahertz Phase-Matching [PDF]

open access: yes, 1999
Traveling-wave THz photomixers based on angle-tuned optical/THz phase-matching are experimentally demonstrated. A dc-biased coplanar stripline terminated by a planar antenna is fabricated on low-temperature-grown GaAs.
