Abstract

An improved, dual diode convergence module which focuses the light energy of at least two separate diode chip laser wavelengths of into a single beam and, thus, which derives the benefit of both wavelengths.

a) a base housing containing means for control of at least two diode chip lasers;

b) at least two diode laser chips each emitting a diode chip laser output beam having a separate wavelength, wherein at least one diode chip laser output beam comprises infrared light of an optimal wavelength of 800 nm;

c) means within the housing and interposed between the diode laser chips for spacing the diode laser chips and aligning each respective diode chip laser output beam;

d) separate means for focusing each diode chip laser output beam; and

e) means for calibrating each diode chip laser output beam focusing means.

2. The dual diode chip laser converging module of claim 1 , wherein each diode chip laser output beam comprises infrared light of at least a wavelength of 800 nm, and at most a wavelength of 980 nm.

3. The dual diode chip laser converging module of claim 1 wherein the separate means for focusing each diode chip laser output beam comprises at least one aspheric lens housed within means for lens housing, wherein means for lens housing is housed within the base housing.

4. The dual diode chip laser converging module of claim 1 , wherein the means within the housing and interposed between the diode laser chips for spacing the diode laser chips and aligning the respective diode chip laser output beams comprises a laser mounting block having a centerline and at least two side surfaces of acute angle orientation to the mounting block centerline, whereby at least two diode laser chips are affixed to the mounting block side surfaces with the direction of each emitting a diode chip laser output beam oriented towards the block centerline and a corresponding separate means for focusing the output beam.

5. The dual diode chip laser converging module of claim 1 , wherein the means for calibrating each diode chip laser output beam focusing means comprises at least one set screw communicating with each diode chip laser and means within the housing and interposed between the diode laser chips for spacing the diode laser chips aligning the respective diode chip laser output beams.

6. The dual diode chip laser converging module of claim 5 , wherein the means for calibrating each diode chip laser output beam focusing means further comprises at least one set screw communicating with means for lens housing and the base housing.

7. The dual diode chip laser converging module of claim 4 , wherein the means for calibrating each diode chip laser output beam focusing means further comprises at least one set screw communicating with the laser mounting block and base housing.
