A change in drive current equals a change in the devices’ wavelength and output power. Tunable Diode Laser, Velocity, Wide Tuning, 1550-1630 nm Tunable Diode Laser, Velocity, Wide Tuning, 1700-1800 nm All these combined allow us to guarantee very narrow linewidths of less than 200 kHz measured over 50 milliseconds.The fiber-coupled versions feature an integrated optical isolator and a permanently fixed and aligned steel jacketed fiber, eliminating fiber misalignment to increase efficiency and maintain power stability. TLB-6732 DBR or DFB laser diode devices have the Bragg grating wavelength stabilization section directly integrated onto the laser diode chip section. There is no coarse tuning, just smooth mode hope free tuning. We have incorporated our unique magnetic dampening to stabilize the tuning arm and reduce vibrational noise. This is not good for diodes which require a constantly controlled current.

But beyond the obvious reason, here's why: If you purchase a current source with a 2 amp range and the diode requires only 50 mA, pay attention to the current source resolution, it is a function of the total output range. Loading... Tunable Diode Laser, Velocity, Wide Tuning, 1030-1070 nm But in short, a laser diode is a semiconductor device made of two different materials. In most research applications where you are intending to spend hundreds to several thousands of dollars on a laser diode current source, the most important spec's are: One more note about attributes, even though not mentioned in the top three, the current range is of course important. Loading... Tunable Diode Laser, Velocity, Wide Tuning, 1975-2075 nm

We distinguished between a thermal and a current tuning mechanism.

An important specification for laser diode’s used in tunable diode laser absorption spectroscopy (TDLAS) is the laser's tuning coefficient. This is specified on the data sheet as picometers of change per milliamp of change in the bias current, and nanometers …

Tunable Diode Laser, Velocity, Wide Tuning, 1420-1500 nm The DL pro HP diode laser features a special resonator design, which allows for higher single-mode output powers from "visible" laser diodes. High-power laser diodes are tuned to the absorption band of the dielectric crystal resulting in much more efficient pumping of the laser rod, from which a high-power focused coherent beam of light is emitted.
