“…The approach of 24 uses a two-reflection peak fiber Bragg grating as the external cavity mirror together with a saturable absorber to create a Q-switched dual wavelength fiber laser, while the approach of 25 uses an arrayed waveguide grating to generate the desired tunable dual-wavelength output, which is then stabilized by a graphene based saturable absorber. Graphene oxide can also play the same role, as demonstrated in 26 , in which the graphene saturable absorber is used to stabilize the dual-wavelength output of a Nd:GYSGG laser. Besides this, there has also been a recent demonstration on the use of new materials as saturable absorbers, such as MoS 2 27 and black phosphorus 28 .…”

A stable dual-wavelength thulium-doped fiber laser operating at 1.9 μm using a short length of photonic crystal fiber (PCF) has been proposed and demonstrated. The photonics crystal fiber was 10 cm in length and effectively acted as a Mach-Zehnder interferometry element with a free spectral range of 0.2 nm. This dual-wavelength thulium-doped fiber laser operated steadily at room temperature with a 45 dB optical signal-to-noise-ratio.

“…Song et al employed graphene oxide as the saturable absorber, achieving a passively Q-switched mode-locked Nd:GYSGG laser with two output wavelengths at 1057 and 1060 nm. The pulse duration was 441 ps at a repetition rate of 100 MHz [24]. Benefiting from the diversity of upper and lower energy-level Stark splitting, laser transitions that are impossible with common garnet laser crystals can be realized with disordered Nd:GYSGG crystals.…”

Garnet crystals possess many properties that are desirable in laser host materials, e.g., they are suitable for diode laser (LD) pumping, stable, hard, optically isotropic, and have good thermal conductivity, permitting laser operation at high average power levels. Recently, a new garnet material, GYSGG, was developed by replacing some of the yttrium ions (Y3+) with gadolinium ions (Gd3+) in YSGG, demonstrating great potential as a laser host material. GYSGG crystals doped with trivalent neodymium ion (Nd3+) and erbium ions (Er3+) were successfully grown for laser generation in the near- and mid-infrared range, with some of the laser performances reaching the level of mature laser gain media. This paper gives an overview of the achievements made in Nd3+- and Er3+-doped GYSGG lasers at different wavelength ranges. Additionally, full descriptions on Q-switching, mode-locking and wavelength-selecting methods for Nd:GYSGG, and the mechanisms of power scaling by co-doping sensitizers and deactivators in Er:GYSGG, are given. It is expected that this review will help researchers from related areas to quickly gain an understanding of these laser materials and promotes their commercialization and applications.

“…However, recent work show that, relatively stable operation could potentially also be achieved in QML regime [45,46], a stability range that is sufficient enough for many applications where the process also averages out the fluctuations. QML operation have been described in many laser gain media, including Nd:fiber [47], Nd:YVO 4 [46,48,49], Nd:GYSGG [50], Nd:LuVO 4 [45], Tm-doped aluminum oxide glass [51], Tm:CYA [52], Er:YAG [53], Er-doped fiber [54], Prdoped ZBLAN fiber [55]. Various Q-switched mode-locking mechanisms such as nonlinear interferometry [51], MoS2 saturable absorbers [52], self QML [55], saturable Bragg reflectors [53], graphene-oxide [50,54], liquid dye solution [47], Cr:YAG [45,46], V:YAG [46], LiF [46,49], GaAs [46], and acousto-optic modulators [46,48] have been employed in these earlier work.…”
