WebJul 1, 2024 · The laser pulse shape presents a relatively wide falling edge and the simulated pulse width of laser is 1.02 ns. For Vλ/4 < Vhl ≤ 1.4 Vλ/4, the pulse width of laser is found to be narrowed with Vhl increasing, and reaches 0.98 ns at Vhl = 1.4 Vλ/4. WebSep 14, 2024 · For short Q-switched pulses a short cavity length, high gain and a large change in the cavity Q is necessary. If the Q-switch is not fast, the pulse width may be …

WebNov 1, 2024 · The Q-switched pulse width variation with the pump pulse energy is given in Fig. 4(b). The pulse width was less than 1 ns even at weak pump strength, due to the short lifetime of the laser cavity and the high stimulated emission cross-section of … Web8.1 Q-Switch Theory 493 (8.9). Since the cavity transit round-trip time for the given resonator length is about 2 ns, the expected pulse width from the laser is t p = 11 ns according to (8.11). The peak power of the Q-switch pulse follows from the parameters already calculated and is P p = E out/t p = 9MW. 8.1.2 Slow Q-Switching introduce school
