چکیده

An organic semiconductor laser, simply fabricated by UV-nanoimprint lithography (UV-NIL), that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV-NIL laser threshold density of 770 W cm(-2) , establishing the potential for scalable organic laser fabrication compatible with mass-produced LEDs.

Operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser.

We report the operation of an optical in-well-pumped vertical-external-cavity surface-emitting laser. The laser delivers 1 W at 855 nm and is pumped with a cost-effective fiber-coupled laser diode emitting at 806 nm. The laser modal gain is examined and ways of optimizing the system are investigated and discussed.

Diode-pumped Continuous-wave Nd:LuVO4 Laser Emitting at 1086 nm in σ Polarization

A diode-pumped Nd:LuVO4 laser emitted at 1086 nm in σ polarization has been demonstrated. A power of 2.37 W at 1086 nm has been achieved in continuous-wave (cw) operation with a fiber-coupled laser diode emitting 18.2 W at 809 nm. Moreover, intracavity second-harmonic generation in cw mode has also been demonstrated with a power of 528 mW at 543 nm by using a LiB3O5 (LBO) nonlinear crystal.

IN-BAND PUMPING OF Nd-BASED SOLID-STATE LASERS

The author is presenting output performances obtained from Nd-based laser materials that were in-band pumped directly into the F3/2 emitting level. Continuous-wave (cw) laser operation at 1.06 μm with slope efficiency of 0.79 in Nd:YAG and 0.80 in Nd:GdVO4 and Nd:YVO4 was realized using an end-pumping configuration and a tunable Ti:Sapphire laser around 0.88 μm as source of excitation. These sl...

Diode pumped distributed Bragg reflector lasers based on a dye-to-polymer energy transfer blend.

We report the demonstration of a compact, all-solid-state polymer laser system comprising of a Gallium Nitride (GaN) semiconductor diode laser as the pump source. The polymer laser was configured as a surface emitting, distributed Bragg reflector laser (DBR), based on a novel energy transfer blend of Coumarin 102 and the conjugated polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinyl...
