Waveguide laser light source suitable for projection displays |
| abstract |
The invention relates to a semiconductor diode laser used to pump a waveguide and their use as light source. A waveguide laser (15) according to the present invention producing visible wavelength radiation from IR wavelength radiation comprising: a) at least one semiconductor diode laser or diode laser bar (8) producing IR wavelength radiation; b) at least one upconversion layer (13a, 13b, 13c) having a thickness of at least 1 µm thicker than the thickness of the emitting layer in the semiconductor diode laser that converts the IR wavelength radiation into visible wavelengths by an upconversion process of photon absorption energy transfer followed by emission; c) at least one optical resonator which recirculates the visible wavelength radiation and/or at least one optical resonator which recirculates the IR wavelength radiation; whereby - the laser diode or laser diode bar and the upconversion layer(s) are arranged on the same substrate or each on a separate substrate (12, 14); - the laser diode or laser diode bar and the upconversion layer(s) are adjacent arranged, whereby a gap between the adjacent arranged diode laser bar and the upconversion layer(s) is formed; or - the laser diode or laser diode bar and the upconversion layer(s) are contacting arranged in this order; and whereby the waveguide laser has a beam quality M2 of ≥ 2 and ≤ 1000. |
