technical field [0001] The invention relates to a power supply device, in particular to a high-precision intelligent integrated drive power supply for semiconductor light emitting devices. Background technique [0002] Laser instruments and equipment for different purposes have different laser emission wavelengths, optical power, and pulse widths. For example, the emission wavelength of laser pulse rangefinders is generally 1.55 μm, and the optical pulse width is 10 μs; the emission wavelength of laser guidance equipment It is generally 1.06 μm, and the light pulse width is 20-60 μs; the emission wavelength of the infrared phase rangefinder is generally 0.86 μm, and the emitted light wave is a continuous sine wave. [0003] In order to realize the non-contact and non-disintegrating non-destructive testing of the performance parameters of the receiving system of these different wavelength laser equipment, it is often necessary to use the analog laser light source of the corre...
