Passively Q-switched 01-mJ fiber laser system at 153 ?m

Abstract: We demonstrate a passively Q-switched fiber laser system generating pulses with as much as 0.1 mJ of pulse energy at 1.53 mum and a >1-kHz repetition rate. These results were achieved with a simple master oscillator-power amplifier scheme with a single pump source, realized with large-mode-area fiber and multiple reflections upon a semiconductor saturable-absorber mirror.

“…Since the NPR Q-switched laser was unstable against environmental perturbations, only slightly above 10 dB signal-to-noise ratio was observed in their experiment. Q-switched fiber lasers incorporating a real passive saturable absorber (SA), such as a semiconductor saturable absorber mirror (SESAM) [13,14] or carbon nanotubes (CNTs) [8,15,16] have been proposed. A 1.53 mm all-fiber passively Q-switched laser with 0.1 mJ pulse energy based on a SESAM has been reported in [13].…”

“…Also, these elements should control a high light intensity. Hence, two approaches are used to create a high power fiber lasers, namely: the application of bulk control elements [1,2] or the realization of the self Q-switch lasing [3,4]. The first way leads to a complication of the laser scheme then an advantage of the pure fiber design is lost.…”

“…Qswitching in fiber lasers can be realized by a variety of active and passive methods of the cavity parameters' modulation. Among the passively Q-switched Erbium fiber lasers, note a laser with distributed back-scattering [1], a laser with a Gallium liquefying mirror [2], a laser with a semiconductor structure acting as a saturable-absorber mirror (SESAM) [3], and a laser with an intracavity Co 2+ :ZnSe or Co 2+ :ZnS crystal [4]. All the mentioned laser schemes have such a disadvantage that they are not all-fiber systems and their implementation requires difficult alignment settings and needs a special attention to optical damage.…”

“…The coefficient ∆n 20 (formula (4)) is an expression for the change of refractive index (in cm −2 ) providing the existence in a fiber of the fundamental mode of the radius w 0 . In formulas (3,4), λ T and dn/dT are, respectively, the thermal conductivity and temperature dispersion coefficients of silica, and hv g is the laser radiation quanta energy.…”
