Fig. 4: Experimental results of the mechanically assembled laser.
From: Chip-scale high-peak-power semiconductor/solid-state vertically integrated laser
a I–L characteristics. b Single-pulse waveform. The vertical axis was calculated from the obtained pulse energy (12.1 μJ) and the pulse waveform. c Temporal waveform. d Optical spectrum. The data presented in b–d were measured at an injection current of 370 mA.
