Mini Laser Diode
Battery volts and mA question?
I make lasers and my laser driver and diode draw 8 volts and the laser uses 90 mA what is a good battery or batteries that would fit in something about the size of a mini mag flashlight?
you can get 9 or 12 volt batteries that are about the same size as an AA battery, but a bit shorter.
A23 is the 12 volt one and it is good for 40 mA-hr
SP-MINI-9V is the 9 volt one
an ordinary 9 volt battery is pretty small and is good for 500 mA-hr and is a lot cheaper than the other two, and easier to get.

| | 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.

| | 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.

Yesterday, Today and Tomorrow
To my humble opinion, everything in the world is like an opera or a novel. Why? I am a loyal and sincere philosophy believer; so I believe in the development of all things including the living and non-living ones (called in biology). To my eye, all things in the world has life-birth, grow and then death. To an opera and novel, the life is beginning, developing, climax and the end. That is the answer of the above “why”.
Today I would like to take the LED projector as an example to exactly explain its life, that is to say, I will briefly discuss its yesterday, today and tomorrow.
It is known to all that it is until in 2008 that the world saw the appearance of LED projector. Exactly speaking, it is should be called LED light source projector. LED, abbreviation of Light Emitting Diodes is a solid semiconductor device which can transform the electrical energy into visible light. That is to say, it can convert the electricity to light directly.
Before 2008, the projector’s light depends on traditional UHE and UHP bulb. Both of them generate tons of heat when working and they need complex optical structure. And the life is limited. Different from them, LED does not give out much thermal and can enjoy longer life-over 10,000 hours. Apart from what I mentioned above, its brightness and resolution has been close the needs of common commercial and home use. When the first LED projector showed up on the InfoComm exhibition in America, it attracted people’s attention especially those in the same business circle due to its ultra long life span.
In 2009, we all witness the rapid and great development of LED projector. Put aside the weight, its brightness has grown from 10 lumen to 800 lumen, and the resolution from the former 640*480 to the present 1080p-the superb level. So, full high definition image seems a piece of cake to the new LED projector.
With the LED projector drawing more and more attention, there comes out different style of LED projectors. New ones have been integrated into MP4, mobile phone and even the digital camera. Multifunction is the guide. Playing audio, video, supporting SD card, watching TV, recording video… LED projector seems to be a tour de force worshipped by lots of people.
At present, LED is mainly developing for the embedded and entertainment market and accepting appreciation and admiration in most related business. However, it seems difficult to take over more market volume than the traditional projector.
We can bet that there is still a long way to go for it to beat the modern commercial and educational projector. Also, people’s need of higher brightness has become a block for it to break into the commercial market. Though we all witness the breakthrough in brightness, it cannot meet the higher needs of commercial use (2500 lumen) not to mention the 3000 lumen for education as well as more than 5000 lumen for engineering marketing.
Of course, the price is also a factor to impede LED projector for home use. To those who get used to TV and computer entertainment, it is not easy to accept a LED projector which can only be used at night without any decorating effect.
What is more, the new rival or counterworker-laser source has come. It features stronger color gamut and higher brightness. The future of LED projector seems in suspense. For the near future, it is believed that LED projector will play the most important role of entertainment market, traditional light source still takes over the business and education market and the new laser source projector will surely control the engineering field. However, who will integrate the whole projector market?
New things replacing the old cannot be stopped by anyone. Of course, time is the best witness.
