✦ Synopsis

We describe the construction and characterisation of a GaN violet laser diode in a compact, extended cavity geometry. Up to 3.5 mW of single frequency power at 392 nm is generated which is continuously tuneable over 6 GHz and coarsely tuneable over 2.7 nm. We place an upper limit on the linewidth of 5 MHz. The performance of the violet diode laser is compared to that of visible laser diodes in our extended cavity geometry. Possible spectroscopic applications are discussed.

## Abstract ## Introduction: In previous studies we and others have demonstrated the usefulness of violet laser diodes (VLDs) as replacement laser sources for krypton‐ion lasers on stream‐in‐air cytometers. Previously available VLDs had a maximum available power of less than 25 mW; this was suffic

The laser performance of violet InGaN laser diodes is investigated numerically. The polarization-dependent properties, including overlap of electron and hole wavefunctions, threshold current, and slope efficiency, are studied through the use of step-like quantum well structure. Furthermore, the elec
