Q-Switching and mode-locking pulse generation based on passive techniques / Amri Ab. Rahman [PDF]
, 2015 The field of fiber lasers and fiber optic devices has experienced a sustained rapid growth despite witnessing the infamous ‘telecom bubble burst’. All-fiber optic devices have inherent advantages of relatively low cost, compact design, light weight, low ...

Q-switched Nd:YAG optical vortex lasers
Optics Express, 2013 Q-switched operation of a high-quality Nd:YAG optical vortex laser with the first order Laguerre-Gaussian mode and well-determined helical wavefronts using a fiber-based pump beam conditioning scheme is reported. A simple two-mirror resonator incorporating an acousto-optic Q-switch was employed, along with an etalon and a Brewster plate to enforce the ...

Nanosecond Hybrid Q-Switched Er-Doped Fiber Laser With WS2 Saturable Absorber
IEEE Photonics Journal, 2016 We demonstrate a stable hybrid Q-switched Er-doped fiber (EDF) laser with WS2 as the saturable absorber (SA). The SA device is obtained by depositing WS2 on a tapered fiber using the pulsed laser deposition method.

Graphene actively Q-switched lasers [PDF]
2D Materials, 2017 Graphene electro-optic modulators (GEOMs) are emerging as a viable alternative to conventional material-based modulators mainly due to their broadband and ultrafast performance. These GEOMs with combined advantages of small footprint and low energy consumption can potentially enable various high-performance applications that are not possible using ...

Performance of efficient Q-switched diode-laser-pumped Nd:YAG and Ho:YLF lasers for space applications [PDF]
Solid-state lasers pumped by continuous-wave diode lasers can be Q-switched to obtain high peak power output pulses. The dependence of laser-pulse energy, average output power, peak power, and pulse width on pulse-repetition frequency in Q-switched Nd ...
