ABSTRACT:
A semiconductor diode laser tunable within a range of over 200 wave numbers. Increased tuning range of a lead-salt laser, from about 30 to over 200 wave numbers, is attained by providing an increasing majority carrier concentration in the laser crystal within the laser cavity in the direction extending away from the contiguous PN junction contiguous the laser cavity.
