Experiments of a diode-pumped Nd:GdVO₄/LT-GaAs Q-switched and mode-locked laser

Abstract

A diode‐pumped passively Q‐switched mode‐locked (QML) Nd:GdVO4 laser with a low temperature GaAs (LTGaAs) saturable absorber is presented. The maximal Q‐switched mode‐locked average output power was 798 mW with the Qswitched envelop having a repetition rate of 125 kHz. The modelocked pulse trains inside the Q‐switched pulse envelope had a repetition rate of ∼750 MHz. The laser properties of the operational parameters on the pump power were also investigated experimentally. (© 2007 by Astro, Ltd. Published exclusively by WILEY‐VCH Verlag GmbH & Co. KGaA)

Diode-pumped actively Q-switching and mode-locking Nd:GdVO4laser

“…Nd:GdVO 4 crystal, as an isomorph of Nd:YVO 4 , has been confirmed to be a promising laser medium for diode pumping [2][3][4][10][11][12][13][14][15]. As compared with [2,[12][13][14].…”

Passively Q‐switched 1.34μm Nd:GdVO4laser with V:YAG saturable absorber

“…However, most of the previous works were concentrated on its lasing per- formance at 1064 nm, not only for passively Q-switching and self Q-switching [12] but also for Q-switched modelocking intracavity frequency-doubling [13,14].…”

494 nm blue laser based on sum-frequency mixing of diode pumped Nd3+ lasers

“…Lasers emitting in the blue range are useful in many fields, such as medicine, lithography, communications, display or biology. Classical wavelengths of frequency doubled solid state blue lasers are 473, 457, 456, and 458 nm [21][22][23][24][25][26][27][28][29][30]. These lasers are efficient and powerful, and it could be interesting to extend these sources to other wave lengths, in particular to deeper blue.…”
