Pump control based pulse on demand operation of frequency doubled Nd:YVO4.

• Directly pump controlled compact DPSS laser for micro pulse generation. • Gain control in intracavity doubled laser for pulse on demand operation. • First investigation of high modulation intracavity doubled Nd:YVO 4 laser. • Identified optimal parameters for intracavity doubled directly pump modulated laser. • Shown photon lifetime influence on laser efficiency and maximum modulation frequency. Directly pump controlled pulse on demand operation of an intracavity frequency doubled Nd:YVO 4 laser is presented, capable of generating arbitrary delay between pulses in the output sequence with the upper limit in MHz range. Micro pulses on demand were achieved by the gain switching technique and intracavity doubling through the optimization between the conversion efficiency and achievable repetition rate. Further, the article presents first study of a high modulation intracavity doubled Nd:YVO 4 laser utilizing the crystals high emission cross section for fast gain switching. In the free space experimental setup, the highest repetition rate over 2 MHz and frequency doubling efficiency of 30% were achieved with the further scaling possible using optically bonded tightly packed architecture. The demonstrated pulse on demand operation of a compact micro pulsed laser at 532 nm enables full synchronization with the application. [ABSTRACT FROM AUTHOR]
