Cheapest way to power a PHR-803T blu-ray laser diode~Share your opinions!

[thanospetr]

Hello people, it's been a month now that i want to buy a PHR-803T blu-ray laser diode.

PHR-803T blu-ray laser diode in focusing module - $17.99 : Modwerx Shop

This one is ok , right???

But i need a driver as well...Can i use one that i extracted from a green laser???
I want to use it in the romisen lb-030 green host from DX.( DealExtreme: $26.85 30mW Romisen L-B030 Green Laser with GITD Tail (CR123A) )
The power source will be a single CR123 battery.

Will this work or not??? What is the best way to make this laser ?

Waiting for your valuable opinions~~~~~~~:can::can:

You cannot use the driver from the green laser. Unless you build one yourself, this is about the least expensive way to drive that diode

What current would be the best for a high output???

With the driver above ,do i have to use more than one CR123 battery???
Will the aixiz module fit in the romisen host???

I'd use 110mA for a nice output and decent life span. +10mA max, I wouldn't go any higher than 120, it will drop the life span of the diode quite a bit.

any idea about the rest of my questions ?

Your diode needs 5V. That driver needs 1.2V. That means you need a minimum of 6.2V to regulate the laser.

If you must operarte with a single CR123 (3V), then you will need this driver instead

You could also build a DDL current regulated driver even cheaper..
Here's a Thread that will help you do that...

He wants to use a single CR123 (3V) battery for the power source. He already has a host that uses that battery configuration.

To drive a bluray with a DDL driver would require 7V at the battery, no?

Hello again! I am planning to use these parts to make a blue-ray laser:

405nm PHR-803T Blu Ray Diode in Aixiz Laser Module Housing [PHR-803T in Aixiz module] - $19.83 : High Tech DealZ, Simplifying the LASER Hobby! ---------> 19.83$

405nm blu-ray laser diode driver [OLBVD20] - $7.99 : Welcome to O-Like.com, Your source for laser products ----------------> 8+3 $ = 11$ including shipping


They are ok , right??? I am buying this driver because my budget is low now...
Do you think i will face any problems? Will it be difficult to solder these two items together???
I will power this driver with a CR123 3,5 V battery.

I am waiting for your comments guys!

I don't think that is a boost driver...so you will need more than just 1 cr123 you will probably need 2 :san:
Hope this helps,

To drive a bluray with a DDL driver would require 7V at the battery, no?

To operate within spec, it requires a voltage drop of 4.25 volts across the driver: 3 volts for the lm317, 1.25 for the sense resistor. Running a bluray from 2 lithium cells with a DDL circuit is way out of spec for the regulator - so far, i expect chances of failure are very realistic.

Well,Toogoofy I have read several posts in the forum and many people power a phr with this driver using a 4-4.2 V battery (a full CR123 3.6V or 18650)with no problem...
Why is that ?

 

[toogoofy]

oh it appears these are boost drivers
I apologize I missed the 3-5VDC part.
