หลังทำเลเซอร์เสร็จ เช็ดเจลและทำความสะอาดผิว
ทาเจลเย็นลงบนบริเวณที่ต้องการทำเลเซอร์เพื่อลดอาการอักเสบและการระคายเคืองของผิวก่อนเริ่มยิงเลเซอร์
The conventional laser diode cannot be analyzed right until unique lasers are cleaved and examined. While in VCSEL, it could be tested at Each individual phase throughout generation. Hence preserving creation time as well as substance.
Ti:sapphire lasers are typically pumped employing a inexperienced-wavelength CW pump laser. Normal repetition rates of Ti:sapphire oscillators are fifty to one hundred MHz, and peak powers as large as a number of hundred kilowatts.

Balance: Laser diodes have low electric power and wavelength fluctuations after a while and great output steadiness.
มีประสิทธิภาพและเหมาะกับทุกสีผิว ทุกประเภทผิวไม่ว่าจะเป็นผิวบอบบาง ผิวคล้ำ หรือผิวแห้ง
Nonetheless, the lesser the acquire bandwidth of Nd signifies that they're restricted to the 10-ps routine. Their superior peak electrical power and significant repetition rates locate applicability in precision micromachining apps, significantly for thin films and/or for rough materials like chemically strengthened glass, utilizing the filamentation approach just stated.
To accomplish higher pulse energies and better output energy diode laser คือ that are essential for many current and many foreseeable future applications, a fiber oscillator might be mated with a bulk amplifier. If your acquire in the majority amplifier is low, as is the case for Yb-doped rod- or disk-style amplifiers, a regenerative amplifier is employed.
Based on the Power band idea of solids, only content that possesses immediate band gap will launch Vitality in the shape of photons or mild though the indirect band gap will emit only warmth.
Basically , a laser emits a beam of electromagnetic nature that's coherent in mother nature .The working in the laser diode relies on:

Ultrafast lasers are usually outlined as lasers that make pulses while in the choice of five fs to a hundred ps (one femtosecond = ten−15 seconds). If a laser is ready to oscillate in many longitudinal modes, this kind of short pulses can be manufactured While using the so-identified as method-locking approach. With this technique, the modes are locked in section (manner-locking regime) and their coherent interference results in the intracavity optical subject to collapse into just one pulse touring backwards and forwards inside the laser cavity.
