A semiconductor laser device is disclosed that includes a laser resonator situated to produce a laser beam, with the laser resonator including an angled distributed Bragg reflector (a-DBR) region including first and second ends defining an a-DBR region length corresponding to a Bragg resonance condition with the first end being uncleaved and including a first mode hop region having a first end optically coupled to the a-DBR region first end and extending a first mode hop region length associated with the a-DBR region length to a second end so as to provide a variable longitudinal mode selection for the laser beam.
