Pin Laser Diode

The electric field induces because of the movement of the holes and the electrons.

Pin laser diode.

In addition these mounts have the ilx lightwave standard 9 pin d sub input connections to make setup and configuration consistent and easy. 3 laser diodes can directly convert electrical energy into light. In this type of laser diodes an additional confinement layer of a different material is sandwiched between the two p type and n type materials. A pin diode is a diode with a wide undoped intrinsic semiconductor region between a p type semiconductor and an n type semiconductor region.

The wide intrinsic region is in contrast to an ordinary p n diode the wide intrinsic region makes the pin diode an inferior rectifier one typical. The high resistive layer of the intrinsic region provides the large electric field between the p and n region. It covers the widest spectral range from the vis to the nir. A pin diode see figure 1 below is a diode with a wide undoped intrinsic semiconductor region sandwiched between a p type semiconductor and an n type semiconductor.

This entire pin diode p type intrinsic n type arrangement is enclosed normally in a metal casing. The laser diode is electrically equivalent to a pin diode. The lm14s2 universal 14 pin butterfly laser diode mount is designed for use with lasers optical amplifiers and two port electro optic devices in a 14 pin type 1 2 or 2 with bias t butterfly package. Description this 100mw laser module emits a small intense focused beam of visible red light.

The diode in which the intrinsic layer of high resistivity is sandwiched between the p and n region of semiconductor material such type of diode is known as the pin diode. The top surface has heat sink fins and a recessed region to mount the laser diode resulting in a. All standard mounts in the ldm 4980 series feature fully configurable laser and temperature control connections. This is a low power laser device however as wit.

Driven by voltage the doped p n transition allows for recombination of an electron with a hole. Types of laser diodes double heterostructure laser diode. A laser diode ld injection laser diode ild or diode laser is a semiconductor device similar to a light emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode s junction. Our semiconductor laser diodes come in a variety of packages including standard ø5 6 mm and ø9.

This allows the flexibility to accommodate virtually any laser diode pin configuration. Silicon is commonly used as an inexpensive detector material in the vis range. For higher demands ingaas is used. We also offer quantum cascade lasers qcls with center wavelengths ranging from 4 05 to 11 00 µm.

Laser diodes which are capable of converting electrical current into light are available from thorlabs with center wavelengths in the 375 2000 nm range and output powers from 1 5 mw up to 3 w. Laser diode module tutorial.
