Abstract
An optical beam splitter arrangement comprising two beam splitter mounts one of which is turnable relative to the other by flexing a deformable connection. By controlling the turn angle of rotation it is possible to use the light reflected by one of the beam splitters to monitor the output power of a laser and to use the light reflected by the other beam splitter to monitor the wavelength transmitted by the laser.
Claims8
A beam splitter apparatus (10) comprising a first beam splitter mount (30) and a second beam splitter mount (40), the first beam splitter mount being coupled to the second beam splitter mount by a deformable connection (50), the beam splitter apparatus being characterised in that, in use, a force is applied to the second beam splitter mount to rotate the second beam splitter mount relative to the first beam splitter mount.
A beam splitter apparatus (10) according to any preceding claim wherein the rotation of the second beam splitter mount (40) relative to the first beam splitter mount (30) is ten degrees or less.
A beam splitter apparatus according to any preceding claim wherein the beam splitter apparatus (10) comprises a material having a coefficient of thermal expansion of 8 ppm/K or less.
A beam splitter apparatus (10) according to any preceding claim wherein the beam splitter apparatus comprises kovar.
A beam splitter apparatus (10) according to any preceding claim wherein the beam splitter apparatus further comprises a first beam splitter (35) mounted in the first beam splitter mount (30) and a second beam splitter (45) mounted in the second beam splitter mount (40), the beam splitter apparatus, in use, being arranged such that the first beam splitter and the second beam splitter receive light emitted by an optical source.
