Surface-emitting semiconductor laser |
摘要 |
A laser suitable for intra-cavity laser absorption spectroscopy and for telecommunication system comprises a Bragg mirror, a multiple quantum well active region and an anti-reflective coating together with a second mirror spaced from the coating to define an external cavity, the free spectral range of the sub-cavity defined by the coating and the active region being less than two times the bandwidth of the coating and the bandwidth of the Bragg mirror being at least as great as the free spectral range of the sub-cavity.
