ABSTRACT:
Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section, a motion section, and an actuator. The base section includes a proximal and distal portion, and the laser and the dispersive element mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member positioned at the proximal portion and the reflector positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member. The actuator is in selectively engagable abutment against the distal portion of the motion section to move the reflector with respect to the dispersive element about the torsional member to tune the external cavity laser.
