## Abstract Nitride based violet laser diodes grown on GaN substrates have been investigated. A grooved substrate, having a striped pattern with a pitch of 400 ΞΌm, has been prepared and epitaxial growth has been performed. No cracks have been observed in the epi‐layers. The violet laser device has
