I think we need more clues than that. The link only takes you to the OSRAM website and typing, "Hybrid", into the search function got me as far as it probably got you.

Any further info?

Pics?

Other links?

This sums it up.

Introduction ​
[FONT=Arial,Arial][FONT=Arial,Arial]The SPL LLxx (SPL LL85 and SPL LL90) are hybrid laser modules. Additional to the laser chip the module contains two capacitors and a MOSFET which act as a driver stage. The two capacitors are connected in parallel to sum their individual capacitance of 47 nF. The SPL LL85 and LL90 differ in their emission wavelength of 850 and 905 nm respectively. The specified optical peak power is 14 W for the SPL LL85 and 25 W for the SPL LL90. [/FONT]
[/FONT]

Principal of operation ​
[FONT=Arial,Arial][FONT=Arial,Arial]The capacitors are charged using a constant DC voltage. Each time the gate of the MOSFET is triggered, the capacitors are uncharged via the laser chip leading to a short and high-amp current pulse. These high-amp current pulses are required to obtain the high peak power laser emission. [/FONT]
[FONT=Arial,Arial]The pin configuration of the SPL LLxx laser diode is as follows: [/FONT]
[FONT=Arial,Arial]Pin 1: Trigger signal for the MOSFET gate [/FONT]
[FONT=Arial,Arial]Pin 2: Charge voltage [/FONT]​
[FONT=Arial,Arial]Pin 3: Ground [/FONT]

Uhm, looking at the case and electrical specifications, i see only one possible use, for those lasers ..... very compact pulsed rangefinders ..... pulses of nanoseconds at 1Khz rate maximum, are not enough for data transfers, and the peak powers are too high ..... and, being the power referred to peaks and short time pulses, are also unhelpful for any cutting/engraving use ..... but, at that rates, and with a decent optic system, can be used for rangefinders simplifying the usual needed circuitry (cause they already have built-in both the discharge capacitors and the mosfet driver chip) .....

Can't imagine any other practical use, at the moment .....

From their documentation other applications include:

Applications / Benefits

Applications: - Laser range finding - automotive LIDAR sensors: adaptive cruise control (ACC) - collision avoidance - pre-crash detection - fog monitor Benefits: - fully automotive qualified according AEC-Q101 - Cost effective solutions - integrated driver circuit for improved EMC and low voltage operation

So you were right HMNL9, range finding. Very astute!

LOL ..... sorry, i never seen that applications/benefits page, just looked at the diode case and closed the page ..... my bad being in hurry :p :D

yea it does look pretty interesting. how much does it cost? probably be a pain in the ass to house and focus though :undecided:
Click to expand...

it is $48 for the 25 Watt and $72 for 70 Watt... i found these things in the strangest place, i use them to get components for circuits and drivers but high power lasers? it defiantly cough my eye but then again so dose anything with the word "LASER" in it :D

70Watt: SPL LL90_3 OSRAM Opto Semiconductors Laser Diodes

25Watt: SPL LL90 OSRAM Opto Semiconductors Laser Diodes

if anyone gets one let me know id like to see it in action :D
