Abstract In this work, we reported the room-temperature continuous-wave operation of 6.0 W GaN-based blue laser diode (LD), and its stimulated emission wavelength is around 442 nm. The GaN-based high power blue LD is grown on a c-plane GaN substrate by metal organic chemical vapor deposition (MOCVD), and the width and length of the ridge waveguide structure are 30 and 1200 μm, respectively. The threshold current is about 400 mA, and corresponding threshold current density is 1.1 kA/cm2.

We developed an ultrafast photocrosslinking method using a low-cost blue laser diode. Cell-laden hydrogels can be crosslinked within 10 seconds with over 90% cell viability. A microtube was fabricated using the system for bioprinting applications.
