May be it will be interest of you.
I have developed the special driver - APC circuit which size is so small, that allows to place on together with a laser diode.
The size of the chip driver constitutes only 2.59mm X 1.93mm.
This construction of integrated laser diode and chip of the driver - all on one M-248 (LO-11).
Also, this CW driver successfully approaches for installation in HHL package.
I have reached result, when temperature of the chip of the driver (CW mode) does not exceed 38 - 40 degree
cent., without additional heat removal at operating current 1.4 Amp. laser diode.
Driver IC circuitry provides a low power dissipation and cool chip.
Together with the chip of a laser diode and combined with the chip of the driver is functionally finished unit and allows to develop new progressive laser systems.
This diode laser systems is a compact, solid-state driver/laser that is significantly smaller than most current systems, making it easy to install and service.
Full process assembly highly reliable solid state driver and laser diode all on one package gives strong modules,
for example laser systems for applications: solid state laser pumping, graphic arts, illuminations, materials processing.
