What is a semiconductor laser?

A semiconductor laser is a light-emitting device that can generate carriers by injecting carriers into a PN junction of a semiconductor by an electric current. Lasers generated by semiconductor lasers have characteristics of good monochromaticity and good directivity, and therefore are used in many fields.

The color and intensity of light are very important criteria.

The laser has a good monochromaticity.

Long wavelength is red、 Short wavelength is blue-purple

Wow ・Directivity and coherency

Go straight with the same width

Laser light is light that does not exist in nature. In laser, the electron transition occurs artificially. In other words, in laser, electron transition occurs in specific time. All the photons emitted in laser have the same energy, frequency, or wavelength. For example, sunlight is composed of light of various wavelengths and appears white, But the laser has a specific wavelength. Such as a 405 nm laser exhibits a clear blue-violet color.

・ Reduces the effects of dust and other deposits and prevents damage to the laser chip during processing.

・A metal cap welded to the stem. It plays the role of chip protection.

・ A light-emitting portion formed of a compound semiconductor. To a large extent determines the performance of the product.

・It is the chip solid part of the laser chip used to optimize the shape of the light and adjust the position of the light-emitting point.

・It is a round package that is easy to handle. It also acts as a heat sink to dissipate the heat generated by the laser chip,

so it is recommended to design it to be a more heat-dissipating structure when in use.

・ It is a photodiode for stable control of light output. Some products do not have built-in monitoring photodiodes depending

on the product.

Outline of operation such as reproduction / recording of optical disk

The lens concentrates the light from the semiconductor laser and illuminates it on the uneven part of the disc. The reflected light returns to the light receiving element and it is converted into an electrical signal that is ultimately converted into music and video data. Supplemental ・The surface unevenness of the disk has several lengths, with 0 and 1. Digital signal information ・Diffraction grating divides one light into two or more for easy reading Take the signal on the disc

Laser diode characteristic parlance Parlance Symbol Description

Absolute Maximum Ratings － Limits not exceeded under any conditions of use or test conditions.

DC light output Po Output of light extracted from the laser. This is the maximum allowable output when continuous operation or pulse operation is performed. Pulse light output Pp

DC reverse voltage Vrl,Vrd,VR Maximum allowable voltage when reverse bias is applied to semiconductor laser and monitor photodiode.

Operating temperature Top（c） Ambient temperature in operating state of semiconductor device.

storage temperature Tstg Temperature at which the function of the semiconductor element can be saved without any voltage applied.

Threshold current Ith As shown in Figure 2, it belongs to natural light before point A, and the current IF of the laser is excited at point A

Operating current Iop The forward current required to produce the required power.

Operating voltage Vop The voltage required to produce the required power.

Peak oscillation wavelength λp The peak oscillation wavelength at which the semiconductor laser operates. In the case of multi-mode, it is defined by the wavelength of the maximum light intensity of the oscillating spectrum. (image 3)

Output current Im When the output of the semiconductor laser is specified, the specified reverse voltage is applied to the current value at the time of monitoring the photodiode.

Beam divergence angle θ//,θ⊥

As shown in Fig. 4(a), the laser emits a certain divergence when it is emitted. When the distribution is measured with respect to the bonding surface in the horizontal direction (x direction) and the vertical direction (y direction), as shown in FIG. 4(b), the width of the dot at 1/2 of each peak intensity ( The full-width half-turn is expressed as θ//, θ⊥. As shown in Fig. 4, θ//, θ ⊥ = a + b.

Far-field image ripple Rl As shown in FIG. 5, ripple may occur in terms of radiation characteristics. Our company specifies a certain intensity range of 25% or higher of the peak intensity.

Synchrotron axis deviation angle

Δθ//

Δθ⊥ The angle between the optical axis and the reference plane is expressed by Δθ//, Δθ⊥ in the horizontal direction and the vertical direction, respectively. 4(c) でΔθ//, Δθ⊥=(a-b)/2.

Synchrotron axis deviation position

Δx,Δy,Δz The deviation of the chip position in the x, y, and z directions. (Δx, Δy is the deviation of the package from the center, and Δz is the deviation from the reference plane

Slope efficiency ηd The average added value of the light output per unit drive current in the laser oscillating region. η=ΔIF/ΔPO

Interference pattern intensity ratio

α It is a parameter indicating laser coherence. When a laser beam is used to form interference fringes, it is represented by the attenuation rate of its sharpness. The closer α is to 1, the better the coherence characteristic, and when it is 0, it becomes incoherent light.

Astigmatism ΔAS

As shown in FIG. 6, the visual focus position of the semiconductor laser is different between the direction perpendicular to the joint portion and the horizontal direction, and the distance between the two focal points is called astigmatism difference, and the astigmatic difference is large, in order to converge. The beam needs to be corrected.

sensitivity S When the semiconductor laser reflects incident, it flows through the photocurrent of each unit of light output that monitors the photodiode.

Dark current ID Leakage current flowing to the monitor photodiode when a specified reverse voltage is applied in a state where light does not hit at all.
