Using a novel silver nanorods absorber with a localized surface plasmon resonance absorption peak at 1.06 μm,
we obtain a diode-pumped passively Q-switched (PQS) Nd,Gd:CaF
2
disordered crystal laser output. Its PQS
pulse laser performances are studied comprehensively and systematically in this Letter. The single pulse energy
and peak power can be attained to 2.15 μJ and 2.06 W, respectively.

Passively Q-switched (PQS) solid-state lasers at 1.06 μm
have a wide range of application prospects in scientific
research, medical treatment, and even laser cosmetology
due to their high photon energy, wide absorption
bandwidth, and easy thermal management
[1]
.Two
key factors affect the PQS laser performances, laser mate-
rials, and saturable absorbers (SAs). On the one hand,
the progress of materials used as SAs has promoted the
advancement of pulse lasers. Very recently, when the
research boom of two-dimensional materials such as gra-
phene
[2–5]
, transition metal dichalcogenides (MoS

,WS

,
etc.)
[6,7]
, topological insulators (Bi

, etc.),
and black phosphorus (BP) has not yet subsided, metal
nanomaterials, one of them, have attracted increasing
attention due to their interesting optical properties and
application prospects
[8–23]
. This is because noble metal
nanoparticles dispersed in dielectric media exhibit ultra-
fast nonlinear optical responses around localized surface
plasmon resonance (LSPR), resulting in potential applica-
tions in SAs
[8–10]
. Most importantly, the LSPR peak is var-
iable by controlling aspects of the nanomaterials
[9–13,15,18–21,23]
.
Moreover, the large third-order nonlinear and fast
response time as a time scale of few picoseconds are
also excellent nonnegligible optical properties of metal
nanomaterials
[13–15,21–23]
.
Silver nanorod s (SNRs), a component of these typical
metal nanomaterials, have also played a significant role
in photonic device applications, especially as a wideband
SA for versatile pulsed lasers
[15–17]
. A large third-order op-
tical nonlinearity (χ
ð3Þ
≈ 10
−10
esu) of silver nanoparticles
dispersed in polyvinyl alcohol/tetraethyl orthosilicate
matrix has been obtained using a single-beam Z scan
technique
[14]
. Moreover, in a PQS erbium-doped fiber laser,
2.4 μs pulses were generated containing silver nanopar-
ticle-based SAs
[16]
. These results indicate the potential
and advantages of SNRs as SAs. But at present the appli-
cation of silver nanomaterials in all solid-state lasers is still
relatively rare.
On the other hand, laser materials, as the core and foun-
dation of the development of laser technology, have had a
landmark effect on the development of solid-state lasers
[24]
.
Compared with other laser materials, alkaline earth AeF

fluoride crystals (Ae: Ca

, etc.), with the
unique advantages of low refractive index and thermal
lens effect, spontaneous long fluorescence lifetime, and
good thermal stability, have special value applications
in the field of solid lasers. Particularly, the AeF

have excellent laser outputs
[19,25–34]
. The addition of
non-optically active ions (Y

) could
effectively relieve the pernicious concentration of
quenching, and significantly improve their absorption,
emission, fluorescence lifetime properties, and their laser
performance
[26,27]

co-doping Nd:CaF

and their laser performance
[26]
. Then, Qian et al. increased
the Nd,Y:CaF

901 mW
[28]
. In recent years, extensive researchs on
