Diode Driver Power

DIY laser questions...?

i've always been interested in buying a high powered laser, but couldn't justify spending the money. This semester i'm taking a photonics course and i want to purchase one to display and show off for my final project. i've decided to make my own. i'm having a hard time finding information on the subject.

i'm thinking about buying this diode (http://laserdiy.com/350mw-400mwbluelaserdiode.aspx)
and also a driver form the same site.

i know it would be a good idea to buy the Aixiz laser housing, but should i buy a Lens? if so where?

my budget is around $100

any suggestions on diodes drivers ect. will be GREATLY appreciated

I pretty sure i saw a youtube vid where they made lasers using the laser out of an old DVD or CD player. it was very detailed. you should be able to find it.

Study of Laser Diode and Edfa $111.53 This book basically gives the over view about The properties of erbiumdoped fiber amplifier (EDFA) such as gain and noise figure have been studied. By determining the characteristics of the 980nm, 1480nm 1550nm laser sources and ASE (amplified spontaneous emission) at the output of the amplifier used to determine the gain and noise figure of EDFA. This model allows to follow the signal (1550nm), pump (980nm) and ASE as they propagate along the fiber and determine population inversion .The both forward and backward propagation ASE are important in determining the overall gain and noise figure. For the amplification of more than 80 channels the DWDM (Dense Wavelength Division Multiplexing) has required CBand (15251565)nm and LBand (15651610)nm EDFA.We show that a flat gain spectrum can be achieved in the range from 1565 to 1610 nm when the EDF length, pump power and pump configuration are appropriately chosen. Special care must be taken when selecting the EDF length.

Filter Driver $82.85 High Quality Content by WIKIPEDIA articles A filter driver is a Microsoft Windows driver that adds value to peripheral devices or supports a specialized device in the personal computer. It is a driver/program/module that is inserted into the existing driver stack to perform some specific function. A filter driver should not affect the normal working of the existing driver stack in any major way. Written either by Microsoft or the vendor of the hardware, any number of filter drivers can be added to Windows. Upper level filter drivers sit above the primary driver for the device (the function driver), while lower level filter drivers sit below the function driver and above the bus driver. Filters may work on a certain brand of device such as a mouse or keyboard, or they may perform some operation on a class of devices, such as any mouse or any keyboard. Another type of filter driver is the bus filter driver, which may be added on top of the bus driver. For example, an ACPI bus filter is added to support power management for each device.

Simulation of Ingan Blue Laser Diode $172.06 In this book, the design of InGaN LDs structures including multi quantum wells (MQWs) active region device are described and investigated by integrated system engineering technology computer aided design (ISE TCAD) device simulator. The parameters of the LDs structures are varied and optimized for high performance. This optimization study involves aspects such as thickness of active region, doping, thickness of stopper layer region, thickness of quantum wells and quantum barriers, number of quantum wells and several approaches to improve and achieve high efficiency, low threshold current and high output power of InGaN LDs. The basic LDs structures treated here are FabryPerot type InGaN double heterostructure (DH), separate confinement heterostructure (SCH) and multi quantum wells (MQWs).High performance LD has been obtained by using multi quantum wells incorporated with the optimized parameters. The lowest threshold current, higher external quantum efficiency and characteristic temperature are obtained when the number of InGaN well layers is two, at our laser emission wavelength of 415 nm, which is related to the problem of inhomogeneous carrier.

How to repair HP Pavilion DV5t AC Adapter

My hp notebook uses a HP Pavilion DV5t AC Adapter(http://www.usadapter.com/Laptop-HP-Adapter/HP-Pavilion-DV5t-AC-Adapter.html) that has an output voltage of DC18.5V 3.5A. One day the hp AC Adapter stopped working.
I decided to try to repair the adapter. In the past I repaired several switching power supplies of PCs and also one AC-power adapter of a Asus notebook. I found out that most of the supplies had similar defects. Often they are ease to locate and to repair.
This Instructable shows how to repair a hp AC Adapter but using the same principles it can work with any switching power supply.

First of all you need the defective power supply.You need a screw driver. It could be phillips type or a flat blade type, depending on the power supply.
To find out the dead parts you need a multimeter that contains a continutiy and a diode test.
Having a soldering iron and and some pliers is also helpful when replacing parts.

step 2 Opening the case
The HP AC Adapter(http://www.usadapter.com/Laptop-HP-Adapter/) is not meant to be opened. The case is made of two plastic frames pressed together and melted at the contact to one piece.

step 3 Examining and understanding .
Start locating the parts of the laptop ac adapter. We concentrate only on a few parts. I often found out that these are the most critical parts. Most swicth mode power supplies die when being switched on. At that moment a high current flows on the primary power side. You can see that if you plug in the power chord and have a look at the socket. Sometimes you can see sparks that are caused by the high current.

step 4 The Fuse
Start with the fuse. Turn you multimeter to diode test (continuity test) and put the test cables on both ends of the fuse.  The multimeter should “beep” and show a very low voltage (3mV on the picture). If that is the case the fuse is ok and need not be replaced. Otherwise you have to desolder the fuse and put in a new one.

step 5 The Rectifier
Next part in the chain is the rectifier. In nearly all cases I saw til today there is a full bridge rectifier used. Here it is a flat one located near the power connector. Again use the diode test for measurement.

step 6 The Capacitor
Now use our Multimeter in diode mode to find out if the capacitor works.

Place the measuring pins on the pins of the capacitor and look at the display while doing that. As soon as you place the pins the display shows 0V. Then the voltage in the display starts growing and the display shows infinite. Exchange the measuring pins. The same thing happens again. If you are using a multimeter that has got a beeper, you can hear a short beep when connecting the pins.

step 7 Repairing
After we found out what went wrong we can repair the power supply.

If the capacitor is broken, desolder and replace it. I tried to find out if this was the only defect part and decided to do further testing before trying to buy a replacement. I did not have the capacitor that was used in the power supply and had to use a near replacement.

If using other capacitors than the original ones you have to respect some rules in order not to burn some things down.
