All-solid-state gain-switched Cr4+:forsterite laser
No full textWe developed an all-solid-state Cr4+:forsterite laser pumped by a kHz Q-switched diode-pumped Nd:YAG oscillator. The laser is tunable from 1190 to 1310 nm, and generates pulses with duration 70-100 ns and maximum energy 14 uJ at 1230 nm, corresponding to a pumping efficiency 10%. This system could be employed as a regenerative amplifier in an ultrafast all-solid-state system based on Cr4+:forsterite
430-mW single transverse mode diode-pumped Nd:YVO4 laser at 671 nm
No full textA diode-pumped Nd:YVO4 laser operating at 1342 nm and intracavity doubled has been developed. Employing a type II noncritically phase-matched LiB3O5 (LBO) crystal, we generated 430 mW at 671 nm in single transverse mode. Operating at 85% of the maximum output power we also selected a single axial mode
Efficient 1.9 W green diode-pumped cw intracavity doubled Nd:YVO4 laser
No full textEfficient conversion of infrared cw radiation from 1064 nm to 532 nm is reported for a diode-pumped Nd:YVO4 laser, intracavity doubled with a KTP crystal. Pumping with a 10-W fiber-coupled array, 5 W at 1064 nm are measured and as much as 1.9 W at 532 nm. Single-frequency operation is also observed
Efficient intra-cavity second harmonic generation by a diode-pumped actively Q-switched Nd:YAG laser
No full textA compact and efficient intra-cavity doubled, actively Q-switched diode-pumped Nd:YAG laser has been developed. It generates as much as 1.55 W at 532 nm, with pulses of 400 ns at a repetition rate of 15 kHz, with an overall optical-to-optical efficiency of 15.5%. A beam quality factor M2 ≈ 2.35 has been measured at this power level

No full textAncora sul "negotio chaldeo", ovvero gli esordi falliti della stampa in caratteri siriaci orientali (Roma, 1587-1588)
No full textThe article follows up on a previous study concerning the beginnings of the East Syriac typography (The Chaldean Business. The Beginnings of East Syriac Typography and the Profession of Faith of Patriarch Elias (Vat. Ar. 83, ff. 117-126), «Miscellanea Bibliothecae Apostolicae Vaticanae» 20 [2014] 211-258). A more accurate interpretation of documents in the State Archive in Florence allows the author to specify the dates when the punchcutter Robert Granjon designed two East Syriac fonts, thus providing the necessary tools for the printing project. The essay also suggests an identification of the Syriac types of the Stamperia Medicea, through a comparison with other documents relevant to the history of the Eastern types owned by the Stamperia after the end of its activity (1614). As a conclusion, a list of all Syriac types designed by Granjon is proposed
