“…In 2006, Shachkin proposed a special laser resonator which reduced the influence of a thermal lens induced in Er:Yb:glasses and obtained a pulse energy of 1.4 mJ laser output, but the pulse width was 26 ns. [13] Compared with stoichiometric MgAl 2 O 4 spinels, the alumina-rich spinel exhibits better optical, thermal and mechanical properties. Jiang used an alumina-rich spinel (Mg 0.4 Al 2.4 O 4 ) as passive Q-switcher in Er:Yb:glass laser, and obtained a laser output with a pulse energy of 4.8 µJ and a pulse width of 3.5 ns in 2011.…”

A Co 2+ :spinel passively Q-switched erbium-ytterbium-phosphate glass bonded laser pumped at 940 nm is reported. A pulse energy of 210 µJ, a peak power over 70 kW, and beam quality M 2 parameter of 1.2 are obtained under a pump power of 235 mW. An unbonded laser output experiment with the same dimension of the active material and the saturable absorber as the bonded laser output experiment is carried out. The reason why the output in the bonded laser is improved is determined.

“…Compact high efficiency diode pumped lasers are required for modern optical systems. Passive Q-switch application for laser pulse generation is preferable for portable and low power consumption laser heads [5,6]. Development and optimization of passively Q-switched lasers with specified output radiation dynamical characteristics require adequate modelling of the laser mode evolution within the cavity.…”

The influence of amplified spontaneous emission (ASE) on the dynamic characteristics of transversely diode pumped erbium-ytterbium glass laser with Co:spinel Q-switch has been investigated. ASE cavity loss coefficient for passively Q-switched laser has been determined. The dependences of ASE cavity loss coefficient on the active element length, output mirror reflection coefficient, and initial transmission of the passive Q-switch have been defined. Laser dynamics has been modelled on the basis of the rate equation set for ion population densities and photon numbers, taking into account the amplified spontaneous emission. It has been shown that ASE accounting does not influence significantly the energy and duration of the output laser pulse. Variations of the laser turn-on time and pulse repetition rate of about 5-10% have been revealed in the case of ASE taken into consideration.

Lasing dynamics of diode-pumped Yb – Er laser with a passive Q switch exposed to high-power external light

The temporal dynamics of diode-side-pumped Yb – Er laser, with a passive Co2+ : MgAl2O4 Q switch illuminated by a light beam (total fluence of 0.15 – 0.16 J cm−2) from a semiconductor pulsed module, is investigated. It is shown that, using this external illumination, one can change the lasing onset delay and the time jitter ΔT gi. The dependence of ΔT gi on the interval between the instant of switching the illumination module on and the lasing peak position t i has a minimum at |t i| ≈ 10 μs. The decrease in ΔT gi with a change in |t i| from 90 to 10 μs indicates that instant of lasing peak occurrence for the Yb – Er laser is partially controlled by the pulse from the highly stable semiconductor module. If |t i| < 10 μs, the enhanced luminescence fluence in the cavity of Yb – Er laser exceeds 0.16 J cm−2; the light beam from the module does not affect much the lasing process in the ytterbium – erbium laser; and, as a consequence, the time jitter recovers the initial value.
