We report on a 200W, 2mJ, 25ns MOPA fiber laser, the last stage of which has a hybrid gain fiber composed of large-core-diameter and small-core diameter Yb doped fibers.
We present an Yb:YAG modelocked thin-disk laser with a record-high average output power of 275 W, a pulse duration of 583 fs and a pulse energy of 16.9 μJ. Furthermore, we present first experiments towards higher pulse energies.
The design ideas of thin disk lasers will be explained in detail. Experimental results for continuous wave operation and for pulsed operation show the capability for building high power lasers with high efficiency and good beam quality, simultaneously. Modelling the thin disk laser behaviour shows the possible power and energy scalability.
We report a Nd3+-doped double-clad fiber laser with a record output power of 20 W at 910nm. A laser conversion efficiency as high as 44% was achieved in CW operating mode.
“Cryolaser” diode laser designs exploit the improvement in semiconductor material properties at sub-zero temperatures to increase efficiency and power. Optimized single 9xx-nm laser bars demonstrate record peak pulse energy of 2 J (1.7 kW, 1.2 ms, −50°C).
We present a CW and Q-switched Ho:YAG laser resonantly dual-end-pumped by four diode-pumped Tm:YLF lasers at 1.908 μm. The maximum CW output powers of 111 W at 2.122 μm have been obtained.
We present a laterally-coupled 1.55 μm AlGaInAs/InP DFB laser monolithically integrated with an optical amplifier, providing an output power of 210 mW with single mode operation exhibiting a record low linewidth of 64 kHz.
We demonstrate record power and efficiency for 1.5micron fiber lasers using a cascaded Raman laser based on a new architecture with output power of 301W at 1480nm and optical to optical conversion efficiency of 42%.
We have demonstrated a high power green watt-order fiber-laser with a Pr3+-doped waterproof fluoro-aluminate glass fiber. The maximum output power of the 522nm laser beam was measured to be 1.53W.
A conceptual design for a laser fusion experimental reactor (LIFT) based on fast ignition and the construction scenario are discussed. The LIFT project consists of 3 phases to 1) demonstrate repetitive fusion burns, 2) generation of electric power and 3) production of tritium and material test, respectively. The critical issues in each phase are tumbling of an injected target and dumping of stirred...
