High-Power Continuous-Wave Directly-Diode-Pumped Fiber Raman Lasers
We describe novel fiber Raman lasers pumped directly by spectrally combined high power multimode laser diodes at ~975 nm and emitting at ~1019 nm. With a commercial multimode graded-index fiber, we reached 20 W of laser output power with a record slope ...

Randomly polarised beam produced by magnetooptically Q-switched laser
Diode-pumped solid-state micro lasers are compact (centimetre-scale), highly stable, and efficient. Previously, we reported Q-switched lasers incorporating rare-earth substituted iron garnet (RIG) film. Here, the first demonstration of the magnetooptical

Diode-pumped, Q-switched Alexandrite laser as emitter for general purpose atmospheric Lidar systems [PDF]
We present design and performance of four prototypes of narrow-bandwidth emitters based on diode-pumped Alexandrite lasers for atmospheric Doppler-Mie, -Rayleigh and -resonance lidar systems. Furthermore, lab results for efficient frequency-doubling into

Study of Fe:ZnSe Laser Exited by Diode Side-Pumped Er:YAG Laser
The performance of a Fe:ZnSe laser was investigated in different schemes of excitation by a pulsed diode side-pumped Er:YAG laser. At the temperature of liquid nitrogen, the Fe:ZnSe laser, pumped by a free running 360-μs Er:YAG laser and demonstrated a ...

Double-clad structures and proximity coupling for diode-bar-pumped planar waveguide lasers
We report, for the first time, fabrication of double-clad planar waveguide structures and their use for multiwatt, diode-bar-pumped, planar waveguide lasers based on Nd3+ and Yb3+-doped YAG.
