This patent application claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,692 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,866 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,753 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; and this application also claims priority under 35 U.S.C. § 19(e) from co-pending U.S. Provisional Patent Application No. 60/487,867 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes.
a first diode laser set, each diode laser in the first diode laser set including a) a lasing medium in a lasing chamber for producing first light including a first wavelength between about 400 nanometers and about 700 nanometers, and b) an output lens for emitting the first light;
5. The display device of claim 1 wherein the output lens for each diode laser in the first diode laser set reduces divergence in at least one direction for the first laser light.
16. The projection-type display device of claim 1 wherein each diode laser in the first set further comprises a photosensor that detects the first light produced by each laser in the first set and outputs a signal indicative of magnitude for the first light.
17. The projection-type display device of claim 1 wherein the at least one optical modulation device comprises three optical modulation devices that are each configured to selective transmission of a primary color.
18. The projection-type display device of claim 1 wherein the at least one optical modulation device comprises a single optical modulation device configured to selectively transmits the first light and the second light.
a red diode laser set, each red diode laser in the red diode laser set including a) a lasing medium in a lasing chamber for producing light including a red wavelength between about 615 nanometers and about 690 nanometers, and b) an output lens for emitting the red light;
20. A projection-type display device, comprising:
