Abstract:
1. A laser system comprising: a laser source; a laser cavity; an etalon structure for receiving a laser input from said laser source and generating a laser output; and the etalon structure comprising first and second substrates on which are respectively provided first and second partially transmissive mirrors which are parallel to each other with a space therebetween, wherein said first substrate has an input surface and said second substrate has an output surface, said input surface and said output surface being substantially parallel to each other and non-parallel to said first and second partially transmissive mirrors, and said laser system further comprises means for rotating said etalon structure relative to said laser input to selectively change an angle of incidence of said laser input on said input surface to cause simultaneous corresponding changes in a length of said laser cavity and a wavelength of said laser output that provide tuning of the laser output wavelength without mode hopping,
