Optimization of passively Q-switched lasers

Thermal, spectroscopic, and laser characterization of Nd:LuxY1-xVO4 series crystals

“…For a certain Nd:Lu x Y 1-x VO 4 mixed crystal, we can find the use of saturable absorber with lower initial transmission (T 0 = 77%) will lead to narrower pulse width and smaller pulse repetition rate, which coincide well with the theory of passively Q-switched laser. 35 Besides, when the Cr:YAG saturable absorber (T 0 = 77%) is employed, we get not only the narrowest pulse width of 6.4 ns but also the smallest pulse repetition rate of 6.8 kHz in Nd:Lu 0.10 Y 0.90 VO 4 mixed crystal. The corresponding pulse profile and pulse trains are shown in Figure 15.…”

Diode Pumped Planar Waveguide/Thin Slab Solid-State Lasers

“…Depending on whether the quality Q is altered by external drivers, the laser can be referred as active or passive Q-switching. In comparison with active Q-switching, passively Q-switched lasers offer advantages of low-cost, reliability, and simplicity of operation and maintenance [29,30]. Passive Q-switching is extensively applied in compact DPSSL.…”
