Abstract

We report a packaged DFB laser frequency-locked to the Kr 1s₂ - 2p₈ transition at 1.54782 micrometers using a novel miniature discharge lamp. This lamp generates more than an order of magnitude larger optogalvanic signal for the same input power than conventional indicator lamps of comparable size. The frequency stability of the laser package is better than 2 MHz, and the fiber-to-laser coupling loss (< 2 dB) is very stable against temperature fluctuations and mechanical vibrations.
