Electro-optic Q-switched Yb:YAG slab laser

Abstract

A novel side-pumped structure with microlens-free diode arrays and a lensduct was demonstrated. This structure is much more robust and simple than traditional approach of a microlens-conditioned diode arrays with a lensduct. A quasi-CW diode arrays side-pumped KD*P Q-switched Yb:YAG slab laser has been demonstrated. An output energy of ∼10 mJ/pulse with pulse width as short as ∼20ns is obtained at 1-10 Hz repetition rate. To our knowledge, this is the shortest pulse width of Electro-optic Q-switched laser output by using Yb:YAG as the gain medium. Output energy as a function of Yb:YAG absorbed energy

Langasite Family Midinfrared Nonlinear Optical Oxide Materials: Structure, Property, and Applications

“…The performance of the pulse laser with 200 kHz repetition rate is comparable to the BBO Q-switched laser with 200 kHz repetition rate and better than the DKDP (10 kHz) [38], LN (7 kHz) [39], and other LGS (30 kHz) [37] Q-switched lasers. Additionally, the observed pulse width of 5.1 ns is also smaller than the narrowest pulse width obtained with DKDP (20 ns) [40], LN (12 ns) [39], and other LGS (7.8 ns) [37] Q-switch lasers. This work represents the highest repetition rate observed so far in the LGS Q-switched laser regime with a pulsed laser wavelength ranging from 1.0 to 3.0 m. These results indicate that LGS can be used as a high repetition rate Q-switch and is free of piezoelectric ringing effects at least at a repetition rate of 200 kHz and that it can provide a practical Q-switched laser with a tunable high repetition rate for many applications.…”

Wide wavelength-tuning of a double-clad Yb3+-doped fiber laser based on a fiber Bragg grating array

“…Yb 3+ :YAG has properties such as long upper level life time, low emission cross section high quantum efficiency, and no concentration quenching, although careful temperature control is required [12,13].…”

Design and interfacial behavior of two series of gemini amphiphiles with different charge positions based on imidazole moiety

“…The synthetic scheme for exo-and endo-BisImC17Cn. and gemini amphiphiles at the air/water interface [11,[29][30][31][32]. Some new features of gemini amphiphiles and bolaamphiphiles were disclosed.…”

“…Gemini amphiphiles can also be regarded as derived from the bolaamphiphiles by adding two alkyl chains to the headgroups. Compared with the conventional amphiphile (single chain, single headgroup), these special amphiphiles have particularly interesting properties both in solution and at the air/water interface [1][2][3][4][5][6][7][8][9][10][11]. For example, bolaamphiphiles can form various kinds of nanostructures in solution systems and show different kinds of conformations at the air/water interface [7][8][9][10][11].…”

“…Bolaamphiphiles molecules in which two polar functional headgroups are linked covalently by one or more hydrophobic hydrocarbon chains [1][2][3][4][5][6][7][8][9][10][11]. Gemini amphiphiles are molecules containing two headgroups and two aliphatic chains linked by a rigid or flexible spacer.…”
