Diode-pumped Nd:YVO4 laser passively Q-switched with graphene oxide spin coated on ITO substrate

Three operation regimes with an L-band ultrafast fiber laser passively mode-locked by graphene oxide saturable absorber

“…This water-soluble property offers many more choices in preparing it for various applications. To make a SA device based on GO, different kinds of hosts or substrates had been demonstrated, such as polymer [20], solution [21], Si/SiO 2 [18], indium tin oxide [22], hydrophilic quartz [23,24], broadband reflective mirror [19,25], tapered fiber [26], and D-shaped fiber [27].…”

Graphene Oxide-Based Q -Switched Erbium-Doped Fiber Laser

“…Absorption of oxygen on graphene opens up the band gap. GO not only enables tunable electronic, optical, and mechanical properties possible by means of controlled oxidation, [17] but also has similar ultrafast characteristics as that of graphene. [18,19] For laser and optoelectronics applications, freespace solid state pulsed lasers using GO as a saturable absorber (SA) have been demonstrated.…”

“…[18,19] For laser and optoelectronics applications, freespace solid state pulsed lasers using GO as a saturable absorber (SA) have been demonstrated. [17,19] In this Letter, we demonstrate a kind of novel graphene oxide absorber fabricated using pure graphite material. By using this material, inserting it into a ring laser resonator, with erbium-doped fiber (EDF) as the active gain medium, we obtain stable 𝑄-switching pulses.…”

Watt-level Q-switched Nd:LuVO4laser based on a graphene oxide saturable absorber

“…Feng et al obtained a 3 W output power in a mode-locked laser by using a graphene oxide saturable absorber, which was the highest output power for the lasers mode locked with graphene based absorbers [9]. Li et al reported a passively Q-switched Nd:YVO 4 laser with graphene oxide for the first time and obtained a 166 mW output with a pulse duration of 113 ns and a repetition rate of 333 kHz [10]. We selected Nd:LuVO 4 crystal as the gain medium in our work.…”
