Quasi-waveguide amplifiers based on bulk laser gain media in Herriott-type multipass cells
Johann Gabriel Meyer, Andrea Zablah, Oleg Pronin
We present here a new geometry for laser amplifiers based on bulk gain media. The overlapped seed and pump beams are repetitively refocused into the gain medium with a Herriott-typ…

Multipass Faraday rotators and isolators
Johann Gabriel Meyer, Andrea Zablah, Kristaps Kapzems +2
Faraday isolators are usually limited to Faraday materials with strong Verdet constants. We present a method to reach the 45° polarization rotation angle needed for optical isolato…
