High efficiency sub-nanosecond electro–optical Q-switched laser operating at kilohertz repetition frequency |
Single pulse shapes at different values of Vhl: (a) Vhl = Vλ/4, (b) laser from OC at Vhl = 1.4Vλ/4, (c) laser from TFP at Vhl = 1.4Vλ/4, (d) combination of the laser from OC and TFP at Vhl = 1.4Vλ/4. |
