Abstract

Low SWAP (low size and weight and power-efficient) laser diode has been a major focus of research in the laser industry. However, achieving high output power by a wavelength-stabilized laser diode with low SWaP and high airtightness is still challenging. Herein, using lightweight aluminum material and a compact structure design, BWT has developed a laser diode that outputs 200 W from 105 μm core diameter NA 0.22 fiber with the weight of 190 g and size of 144×52×17 mm³. The leakage rate of the diode laser is lower than 9.9×10^-9 Pam³ s^-1. At 11 A, the electro-optical efficiency is higher than 50% with 200 W power output. The module’s mass-to-power ratio is lower than the commercially available 200W laser diode from BWT. It is a relatively low-cost approach to low SWaP laser diode applications without complex structural design.
