Laser Components has begun distributing a range of four-pin fibre-coupled diode lasers manufactured by SemiNex. Lasers are available at standard wavelengths of 1,450, 1,470, 1,532, and 1,550nm, and can be custom made at any wavelength between 1,300 and 1,600nm. Optical power is 4W CW, coupled into a 105µm/0.22NA fibre. The lasers feature a small footprint (26 x 13mm), 30 per cent wall plug efficiency, and 50 per cent W/A slope efficiency. The device is equipped with a back-facet photodiode monitor, and a 650nm aiming beam. It is suitable for aerospace, communications, LIDAR, military and medical applications.
