Q12. Consider a He-Ne laser cavity consisting of two mirrors of reflectivities R, = 1 and R2 0.98 The mirrors are separated by a distance d= 20 cm and the medium in between has a refractive index no= 1 and absorption coeficient a = 0. The values of the separation between the modes 8v and the width Av, of each mode of the laser cavity are. (a) dv = 75kHz, Av, = 24kHz (c) ov =750MHz, Av,=2.4MHz (b) Sv = 100kHz, Av, = 100kHz (d) Sv= 2.4MHz, Av, = 750MHz
