Picosecond pulse duration laser–material interactions are extremely complex and much less studied than the physics of femtosecond and nanosecond ablation. Additionally, multimode laser beam structure can inhibit robust analysis and comparisons of e

Much progress has been made in power scaling mid-infrared lasers based on transition metal ions such as Cr2+, Co2+, and Fe2+ in zinc and cadmium chalcogenides. Still, the exploration of the physics of the devices is incomplete. In this work, we analy

In this work, we collect absorption and emission spectra for Fe2+ ions in zinc selenide (Fe:ZnSe) and identify trends from 10.5 to 300 K in absorption and from 5 to 300 K in emission. The absorption spectrum is used to determine free parameters in hi

We report the first demonstration of a Ho: YAG crystal fiber waveguide (CFW) laser operating at 2.09 µm. The CFW structure was produced by adhesive free bonding of holmium doped yttrium aluminum garnet core to an undoped yttrium aluminum garnet clad

The optical fiber geometry is known for rugged, high power laser sources that are preferred for many applications, but is typically limited to the visible and near-infrared regions of the electromagnetic spectrum due to the transmission limits of sil

We report the demonstration of high-average-power passively Q-switched laser oscillation from Fe2+ ions in zinc selenide. A semiconductor saturable absorber mirror was used as a passive Q-switch element. Using a 60% R outcoupler, the pump-limited out

What does it mean to write for change? How do we negotiate the space between hope and critique? Drawing on Dewey's notion of a common faith, this article contemplates what the author learned from Chip Bruce. It suggests that when we compartmentalize
