摘要： A surface-emitting laser (100) includes an active layer (130); multiple reflectors (120, 140) sandwiching the active layer (130); and an electrode pair (160, 170) connected to a power supply, through which a current is injected into the active layer (130). The surface-emitting laser (100) emits at least one laser beam during a current injection period when the current injected into the active layer through the electrode pair during the current injection period is a first current and emits at least one laser beam during a current decrease period when the current injected into the active layer through the electrode pair during the current injection period is a second current exceeding the first current. The current decrease period is after the current injection period. The current injected into the active layer during the current decrease period is lower than the current injected into the active layer during the current injection period.

摘要： A quantum cascade laser is configured to include a semiconductor substrate and an active layer which is provided on the substrate and has a cascade structure formed by multistage-laminating unit laminate structures 16 each including an emission layer 17 and an injection layer 18. The unit laminate structure 16 has, in its subband level structure, a first emission upper level L up1 , a second emission upper level L up2 of an energy higher than the first emission upper level, an emission lower level L low , and a relaxation level L r of an energy lower than the emission lower level, light is generated by intersubband transitions of electrons from the first and second upper levels to the lower level, and electrons after the intersubband transitions are relaxed from the lower level to the relaxation level and injected from the injection layer 18 into an emission layer 17b of a subsequent stage via the relaxation level. Accordingly, a quantum cascade laser capable of preferably obtaining emission in a broad wavelength range is realized.

摘要： A projection device (101) is provided, which is capable of suppressing or preventing problems that result from a light emission delay of a light source (21a∼21c). The projection device (101) includes a plurality of light sources (21a∼21c) respectively emitting a laser light; a scanning part (3) enabling the laser light to scan; and a controller (58) controlling an output of the laser light. In a scanning range including a first scanning range and a second scanning range, the controller controls (58) such that the output has a first light amount in the first scanning range and has a second light amount which is greater than the first light amount in the second scanning range. The projector may utilize as a RGB source a red, a green and a blue laser diode. Differences in the start up time of the laser diodes emitting different colours are measured during the retrace time and taking into account by the controller when depicting an image by using stored values in order to prevent for colour unevenness in a scan line.
