چکیده

In this work we present the development of an accousto-optically Q-switched Nd:YAG/KTP based compact laser producing 35 W of average green power at 532 nm under operation at 20 kHz repetition rate with simultaneous side and end-pumping configuration. 19.4% optical to optical conversion efficiency has been obtained. The width of the green pulses at the maximum operating power was measured to be 165 ns.

High power VCSEL array pumped Q-switched Nd:YAG lasers

Solid-state lasers pumped by high-power two-dimensional arrays of vertical-cavity surface-emitting lasers (VCSELs) were investigated. Both end-pumping and side-pumping schemes of Nd:YAG lasers with high power kW-class 808 nm VCSEL pump modules were implemented. For one application 10 mJ blue laser pulses were obtained from a frequencydoubled actively Q-switched VCSEL-array dual side-pumped Nd:Y...

Tunable subpicosecond dye laser amplified at 1 kHz by a cavity - dumped , Q - switched , and mode - locked Nd : YAG laser

Tunable subpicosecond pulses are generated by synchronously pumping a dye laser with the pulse-compressed and frequency-doubled output of an acousto-optically mode-locked cw Nd:YAG laser. The pulses are amplified at a repetition rate of 1 kHz, using the frequency-doubled output of a cavity-dumped, acousto-optically mode-locked, Qswitched, cw pumped Nd:YAG laser. Amplified transform-limited puls...

High-power diode-pumped Q-switched intracavity frequency-doubled Nd:YVO4 laser with a sandwich-type resonator.

A compact and efficient diode-pumped acousto-optically Q -switched intracavity frequency-doubled Nd:Y VO(4)/KTP green laser is demonstrated. With 0.5-at. % Nd:Y VO(4), greater than 4.6 W of 532-nm average power at a repetition rate of 50 kHz was generated with 17-W pump power, corresponding to a conversion efficiency of 27%. At 10-30 kHz the pulse width is shorter than 10 ns, and the peak power...

Intracavity coherent addition of single high-order modes.

We report on efficient intracavity coherent addition of several single high-order mode distributions in a multichannel laser resonator. The phase locking and coherent addition is achieved by using an intracavity interferometric beam combiner. The principle, configuration, and experimental results with pulsed Nd:YAG Laguerre-Gaussian TEM01 and TEM02 laser beam distributions are presented. The re...

Theoretical Study of Diode Pumped Intracavity Doubled Passively Q-Switched Solid-State Lasers

In recent years, great attention has been paid to high peak power all-solid-state pulsed blue-green lasers [1–4] for some applications such as spectroscopy, display, optical data storage, coherent telecommunications, remote sensing, medicine, etc. Such lasers are generally realized by intracavity or external cavity frequency doubling of cw laser-diode (LD)-pumped solid-state Q-switched Nd-doped...
